Redmi Note 9 Pro 5G vs Mi 10 Ultra / Note 20 Ultra / OnePlus 8T / 8 Pro Battery Life DRAIN Test!

the redmi note 9 pro 5g has proven itself to be a worthy contender in terms of benchmarks charging and camera since it’s the cheapest 108 megapixel smartphone in the world at just over 200 but how does it stack up in a real day in the life drain test well let’s give it a go here against the me10 ultra samsung galaxy note 20 ultra oneplus 8t and oneplus 8 pro the redmi note 9 pro 5g has the largest battery here with 4 820 milliamps all of them have been updated to their latest available software we have android 11 on the oneplus devices and android 10 on the remaining devices all smartphones here are kitted with 120 hertz refresh rates so things are nice and smooth and i’ll be enabling it on all devices we have amoled panels on all phones over here except for the redmi note 9 pro 5g with a lackluster ips lcd which won’t really bode well in terms of efficiency i have dropped the 920 ultra and oneplus 8 pros resolution down from qhd plus to full hd plus so it can match the other devices the highest ppi is the oneplus 8t since it has the smallest screen and the lowest is the note20 ultra since it has the largest screen we’ll be running through 15 different applications throughout the test each app will be opened on each device at the same time for the exact same amount of time with the same screen brightness as i showed you earlier using a lux luminous meter we’ll be jumping between regular apps

social media apps music streaming apps video streaming apps games and even benchmarks really excited to get this one underway this is teknik and without further ado let’s go we’re going to kick start things off here making sure that all phones are currently plugged in with their respective charger at the box sitting at 100 and we’re going to test out the temperature before we get going with the test we’re using an infrared heat gun here with an emissivity level of 0.5 since it seems to be the most accurate for electronic devices and a room temperature of around 22 degrees in celsius remember measuring their temperature at the current moment is pretty much their temperature while charging so it’s not so accurate but after the first interval that charging indicator below the percentage at the top of the screen there will change to an interval instead of charging time interval is at the top right hand corner we have the battery percentage below the branding above the phone and below that percentage we have the peak temperature as well this charging well like i said we’ll change the interval temperature we’re reaching that first 30 minute interval and we have 96 on the redmi 100 on the xiaomi 95 on the samsung 96 on both one plus devices of the year so the xiaomi is doing the best so far and as you can see now we’ve hit that

interval timer the hottest device is now the me10 ultra in terms of interval and peak and the coolest being the oneplus 8 pro very surprising since in my last test it was the hottest it trained the quickest it would be really interesting to see how long it lost this time around with 120 hertz as opposed to the 60 hertz that i tested last time around hitting that one hour mark interval we have 92 percent on the redmi 97 on the xiaomi 90 on the samsung 94 on the 18 now going ahead of the 8 pro with 93 percent hottest interval now is the redmi the hottest peak is still the mi 10 ultra from last time out and the coolest peak at interval is still the oneplus 8 pro for those of you who have yet to notice at the bottom right hand corner i have mentioned the current app right now we’re on shazam and we’re using screen recording on all devices over here and we do have the specifications of each device underneath their actual phone at the bottom over there underneath their chin after one hour and 30 minutes we have 84 on the redmi 90 on the xiaomi with a much smaller battery than the redmi it’s doing a much better job but you guys have to remember that the redmi is using an lcd panel so it’s not going to be quite as efficient and many people have said in comments before when i use lcd screens the lcd panel looks brighter i did use a lux luminous meter at the start of the test i can assure you it is set to the same brightness as the rest of the devices over here only reason it looks brighter is because it’s an ips panel after two hours 77 on the redmi 86 on the xiaomi 78 on the samsung 82 on the 80 still one percent

ahead of its bigger brother the 8 pro which has a 10 milliamp battery a little bit bigger than the 80 but i guess it doesn’t really make a difference it’s pretty much four thousand five hundred milliamps so we have a standard of four thousand five hundred milliamp cells on pretty much all four devices on the right hand side the oneplus 8 pro give or take a little bit and the redmi note 9 pro 5g with a 4820 milliamp hour battery much bigger than the rest but it’s actually doing the worst over here due to that screen as i was saying earlier two hour 30 minute mark 72 on the readme 82 10 higher than that the xiaomi with a smaller battery 73 on the samsung almost neck and neck with the redmi 78s on the 80 still one percent ahead of the 8 pro with the redmi note 9 pro now being the hottest in terms of interval and peak the coolest interval will be in the 80 and the coolest interval and peak being the april since it’s matching the 80 when it comes to intervals three hour mark we have 68 on the redmi note 9 pro 5g redmi note 9 pro 5g what a mouthful to say 78 on the me 10 ultra 69 on the note 20 ultra which is one between the redmi and the samsung here 75 on the 80 still one percent ahead of the eight pro with 74 ridiculous eight pro does have a slightly bigger battery but the 80 does have a much smaller screen as i was talking about when it

comes to efficiency on the redmi the redmi doesn’t only just have an rps lcd screen but it’s also using a mid-range snapdragon 750g chipset where the rest of the devices are here are using a snapdragon 865 or 865 plus chip run on seven nanometer plus technology which is slightly more efficient than the eight nanometer tech running on the redmi note 9 pro 5g the lpddr5 ram 6 that we see in the mi 10 note 20 ultra and 8 pro also slightly more efficient than the lpddr4x ram slots in the redmi any oneplus 8t after four hours we have 58 on the redmi 70 on the xiaomi the samsung is at 61 now pulling quite a bit ahead of the redmi earlier was just a percent difference between the two the 80 is now pulling ahead of the 8 pro this time earlier it was just a percentage but now 3 ahead and now we’re currently recording using the selfie video camera on all devices i’ve set them to 1080p 30fps even if they can do more than that just so that i can keep things even in terms of the test here as well as comparing to other drain tests on my channel we’ll get to that in a bit 4 hours 31 minutes 51 on the redmi 62 on the xiaomi 53 on the samsung now just two percent ahead of the redmi 63 on the 80 still three percent ahead of the 8 pro with 60 the hottest interval that time around was the mean 10 ultra we’re recording using the backhand now at 4k 30fps and i’ve kept them all at 4k 30fps because the redmi caps

it at that as well as all my other previous trades has been recorded at 4k 30fps during that application time and i want to keep things even so that you can actually compare it and i do compare with a bit of a table at the end so stay tuned for that one five hour mark interval 43 on the redmi 52 on the xiaomi 41 on the samsung 52 on the 80 and 49 on the 8 pro the only 2 still in yellow still above 50 is the xiaomi mi 10 ultra and oneplus 8t very impressed with that oneplus 8t device hasn’t given me any issues in terms of battery life five hours a 30 minute mark we have 34 on the redmi 38 on the xiaomi 27 on the note 20 ultra 40 on the 8t leading the pack now and 37 on the oneplus 8 pro after that benchmark i did run antutu benchmark and then i ran a 3dmark wildlife and now we’re doing gfx page the main reason i do benchmarks is just to simulate high performing games because i can’t exactly play five games on all five devices over here with just two hands and that is the reason i do it and i only do it for one hour because i think that that is more than enough in terms of testing out real performance when gaming i’m not sure if you gearheads out there do go crazy with games all day every day but if you do here’s some mini games after those benchmarks and after those benchmarks we have 24 left on the redmi 14 on the samsung 27 on the xiaomi 28 on the 80 very close between those two the at still three percent ahead of the april 20 now on the april after six hours and 30 minutes 23 on the 18 9 on the samsung 17 on the redmi and 22 on the

me 10 ultra what is happening over here mr samsung i thought that you would do better based on previous tests but i guess 120 hertz i had to use my lux luminous meter to bring it back up since the samsung tends to dim after five percent of battery life and after six hours and 55 minutes the samsung galaxy note 20 ultra cs cheers us honestly this is still incredible battery time i regard anything over six hours of screen on time absolutely incredible will definitely get you throughout the day with more than enough juice left to get you even through to midnight after seven hours we have four phones still going 10 on the redmi 16 on the xiaomi 18 on the 80 and 15 on the 8 pro story 3 gap between the one plus 80 and its bigger brother the 8 pro we’re nearing that seven hour 30 minute mark and all four devices that are remaining make it to that let’s see what’s gonna happen here which one is going to take the cake at the end of the day we have four percent on the redmi after seven hours and 31 minutes nine percent on the xiaomi 10 on the 80 just one percent difference between the xiaomi and the 8c the 8 pro is falling behind now with eight percent which one of those three devices is going to make it i’m pretty sure the redmi will knock out first and it is indeed 7 hours and 44 minutes still absolutely great for a device using a lackluster mid-range 8 nanometer chipset and an ips lcd screen but it does have a bigger battery than the others though not that much bigger to make it reasonable to last a hell of a lot longer but it still did a great job

nonetheless 10 minutes after that 7 hours 54 minutes the phone that cost three to four times the price of the redmi the me10 ultra didn’t do a bad job over there with a milliamp hour per minute reading of 9.49 which is the best out of the three that have capped out eight hours and one minute here three percent on the eighty two percent on the eight pro these oneplus devices are doing an absolutely fantastic job in terms of battery life at 120 hertz refresh rate i would say even better than the 60 hertz option the oneplus 8 pro finally gives up after eight hours and 16 minutes which is still great getting the best milliampere per minute reading and the oneplus 18 not long after that 8 hours 22 minutes just six after the 8 pro but it does have a smaller screen remember so it is understandable absolutely super battery life with 8.96 milliamp hours per minute for the 8t 5th place we have the samsung galaxy note 20 ultra getting six hours and 55 minutes of screen on time with the brightness setting that i set at the start still absolutely phenomenal battery life for a samsung device nonetheless the redmi note 9 pro 5g in fourth place seven hours and 44 minutes almost an hour longer

lasting than the samsung and a hell of a lot cheaper than that we have the xiaomi mi 10 ultra 7 hours 54 minutes just 10 minutes longer lasting then his little brother the redmi note 9 pro 5g is doing credible battery life over eight hours here the oneplus 8 pro 8 hours and 16 minutes 120 hertz refresh rate panel with a 4510 milliamp battery is fantastic even more fantastic first place the oneplus 8t it’s cheaper little brother with 8 hours and 22 minutes not a big gap between the two devices but it does have a slightly smaller battery and an incredible time over there comparing it to screen on time results of all other smartphones on my channel which i have tested with high refresh rate panels during a drain test at the top we still have the huawei mate 40 pro with over nine hours though not quite a big difference between that and the oneplus 8t with a slightly higher refresh rate at 120.

The oneplus 8 pro right behind that the me 10 ultra and redmi note 9 pro 5g pretty much slap bang in the middle of the table and the note 20 ultra quite down low there but not quite the worst not quite the best it still did a fantastic time when enabling 120 hertz i just wish that we could test it out with qhd enabled as well based on previous tests the mi 10 ultra actually did a slightly better time than last time i tested it with 120 hertz the samsung did slightly worse than last time i tested it the oneplus 8t surpassed its last check with 120 hertz but couldn’t quite hit the heights of its 60hz counterparts the oneplus 8 pro did a much better job than the 120hz and the 60hz option since this recent software update that i got improving android 11 optimizations within the device and talking about temps the samsung actually ended off with the worst at 43.

8 degrees in celsius the xiaomi had the highest peak with 56.5 degrees in celsius you could pretty much fry an egg on it at that point the coolest peak on the redmi with 51 and the coolest antenna being on the 8 pro very surprising here considering my last range test with it at 33.8 degrees and celsius i hope that you guys enjoyed watching this video as much as i did making it a sub to the channel would be fantastic this is technic and i’ll see you in the next one
