Battery

Is the battery as bad as the reviewers in YouTube are saying ? I want 6-7 SOT on normal usage.

I get 5-8h depending on what I am doing

I get around 7h SOT on normal usage with wifi on most of the time. Now I got 28% remaining and 5.5h SOT mostly on gaming/youtube. So I guess its not that bad

Most of the time I'll be on 4G tho...
Also how much battery drained while playing that game (im assuming its graphically intensive)

It's a card game, but it has some 3d elements and animations. It drains the battery 1-2%/5 minutes I think.
However, let me tell you this: I've been using Xiaomi Mi3 before (Snapdragon 800 and also 3000mAh battery) and Mi A2 lasts waaaay longer, so I assume some reviewers just look at the numbers and say the battery is weak

I'm in holiday in Bali and have been in 4G since arrival. I use the maps and Spotify for most of the day, play some light games and still have battery life to spare when we get back to the hotel at night.
The phone has great battery for me, but this is all opinions and your milage may vary. Not every has the same requirements for what great battery life is.

Not a good buy to battery life , only 4 sot to me .

I am switching from galaxy s8+. I am using galaxy with full qhd+ resolution almost full brightness.
Will Mi A2 battery work same as s8+?

maybe the worst battery life phone i have used.
in 2018 getting 4Hrs sot is not acceptable from Xiaomi

For as long as people will care about looks then manufacturers will keep making super thin profile phones. If they made them a few mm bigger then could fit a bigger battery.
It's all about deciding what you value the most as you can't have everything your heart desires in one device. Just doesn't make business sense for a company to give you the best of everything at one time.

How much SOT do you get on a S9+? Its around 3-5h. How many times more does it cost? So 4-8h on a 250€ device is fine in my opinion.

I get 6-7 hours before battery reaches to 10 %. Mostly browsing, no games, wifi and 4G mixed.

I come from a s8+ with 5-6 SOT and with the xiaomi I have 5+ SOT, almost the same. Not bad for the price i think

I think 6-7 SOT is possible, depending on what you're doing. If you game a lot or watch loads of movies, then you're really stretching it though. I only got my phone last week, so I haven't tested it that much yet, but so far I can easily get through the day on one full charge.
But I don't play games or watch a lot of YouTube or movies on it. Mainly browsing, emailing, texting, phoning, podcasting, Spotify, a bit of Reddit, etc.
On the plus side, it charges really, really fast, but that's useless if you can't plug it in during the day. Besides that, the Snapdragon 660 is supposed to be more energy efficient than its predecessors. But if battery life is the main issue for you, then you might wanna reconsider buying this phone.
I would have preferred a (slightly) thicker Mi A2 with a larger battery though. 3000mAh really is the bare minimum these days. The phone is great, but it would have been awesome with a bigger battery.
Also, bear in mind, Android One takes up 13Gb of the storage size.

Unhappy with Mi 9 battery draining and SOT, thinking about changing for mate 20 ...

Hi all.
I have written a comment to another created threat in mi 9 forum, but I would like to read your comments here too.
I'm having battery draining and SOT problems with my mi 9, like I said in title (like most people I think).
I have tried everything to improve my battery life in my mi 9, and It's not bad at all, but I was expecting better performance for a top xiaomi smartphone with sd 855 and 5 months old in spite of the fact that it has "only" 3300mah battery ...
I'm not a heavy user and I try to get max SOT and minimum battery drain in all my phones, because I don't like changing smartphones very often and I like to take care of it.
I came from a Moto G4 plus, and I had 5h of SOT in 48h without high standby drainage (maybe 1-2% of drainage overnight in 7-9h) with a 3 years old battery and worst hardware and software. In mi 9, I'm getting 5-6h of SOT in 48-72h. Not bad at all, but standby drainage is awfull. It loses 20-25% of the battery every 48h (3-5% overnight), and in a smartphone with such a fair battery it's a problem. If I'm not getting great results with not heavy use and my smartphone is new, I don't want to think in 2-3 years + mid-heavy use ... I have tried everything (full wipes, reinstalling, the most powerfull battery saving, etc) and I don't have great result. Standby drainage is very hight compared to other phones (I have tried a friend poco f1 and I had 10h in 48-72h with 1% overnight drainage. It was awsome).
And now the question ...
I'm thinking of changing my mi 9 for a huawei mate 20... I still have the 30d Amazon refund and I am not comfortable with my phone's battery.
- Mate 20 pros vs mi 9: +700 mah battery and more efficient, the best ips panel without burn-in problem, and fingerprint sensor behind the screen (no like too much in-screen fingerprint at all).
- Pros mi 9 vs mate 20: sd 855 (but geekbech it's very very similar, and antutu winner is mi 9 only for gamming but mate 20 still on top), unlocking bootloader for mi 9 (better comunity in xda, but if emui works well I think I don't need custom rooms, the problem here is Trump/google vs China ... but now apeares to be solved and we would have newer updates to Android Q), wireless charging (I don't use it because smartphone is hotter when charging 3-5º vs cable+1,5a charger, It takes more time to charge with elevated temperature), not jack (better for waterproof), maybe very little better cameras in mi 9 and little better results, 4 months younger (very little difference) and It's the top phone on xiaomi (mate 20 is the little brother because we have mate 20 pro, 20x, p30, p30 pro and we will have soon mate 20 and mate 20 pro; and that could be worst because we will get latter uptdates in mate 20).
What do you think? Would you change mi 9 for mate 20? Reading your comments. Greetings.

If your looking for better battery life I'd say get the mate 20. I've had mine for just under 3 months. Best damn purchase I've ever made (purchased way below retail during trump ban). I consider myself a medium to heavy user (I don't play mobile games however). With some useless features turned off and some fetch services disabled. I can easily get 8-10 hrs on screen time with this phone, it's the best battery life I've ever had, prior I was getting 4hrs with another Android phone.

Heat? I haven't had any issues with heat if by that you mean does the phone get too hot to touch, it's cool the majority of the time. As for performance, EMUI 9.1 is very smooth and I haven't had any slow downs ??.

Just a month ago I had Poco F1. On the battery Sot was similar to the 20 mate. Night drainage in Poco 1-3%, mate 2-5%. Mate saves better on screen on. Performance similar to Poco. If I had to exchange Mi9, it was on mi9t Pro.

Battery....

So, I dunno what these reviewers and youtubers are up to with these phones, but got mine earlier today (XL), roughly 7 hours ago, and have been using it since.
Phone arrived with 75% charge. Only charging I have done was about 2 20 minute trips plugged into my trucks USB port for Android Auto.
I have everything enabled such as location, soli, smooth display, etc. I use adaptive brightness, ambient eq is off.

I have been very happy with battery life so far. Reviewers are paid to be critical.

My battery life has been excellent as well. I have no idea what these reviewers are doing.

Reviewers forget they have every battery draining social app going, bet they leave Bluetooth, location etc on. Plus they use the camera a but load for testing

I am in agreement as well. seems to be fairly strong with light use and force 90hz checked in dev options for me also. Definitely had worse phones before, definitely better also though. Don't understand the hate though - Pixel 4 XL= 3,700mAh battery, 6.3 in screen vs 1+ 7 pro 4,000mAh 6.67 in. Contrary to popular talk the oneplus 7 pro battery isn't amazing either which is why I don't get the shade.

It all depends what you consider good. Personally I think 6hrs of screen on time staring with a fully charged battery is good, 8+ hours is fantastic. So far the Pixel 4 XL is just barely hitting that good mark for me.
I'm sure that once a few weeks have gone by and kernel devs are on this like a fat kid on a cupcake we'll see guides for extra battery life and other optimizations.

So I've had the Pixel 4 XL , for 3 full days in the UK now.
Day 1 SOT was 6 hrs 3 mins with 9% left
Day 2 SOT was 6 hrs 15 min with 4 % left
Day 3 SOT is 5 hrs 1 min with 18% left.
The battery is more than adequate. I had the 3 XL which would get a max of just over 4 hours. I'm new to the forum but I have screenshots as well but don't have a clue how to upload lol. The phone is on 90hz at all times too but most times you can't really tell. It's an amazing phone so fast, the disappointment is video quality again and some of the pic quality are a similar levels to 3 XL but I need to fully utilise the camera.

Boy I don't know what you guys are doing because I have been getting nowhere close to that in screen on time. I'm at 3 hours is SOT right now with only 30% left

**Update day 4 so 6.49am in the UK, fell asleep so didn't charge currently on 27% with SOT of 4 hrs 3 min which will give me 6 hours comfortably to 0%. After day 1 I forced 90hz on, tap to wake on, pick up wake on too. I may add a few more days updates if anyone is interested.

Battery of my Pixel 4 XL is at best "meh" so far. I noticed problems with several apps running away and draining battery which I would blame on compatibility issues with Android 10. Overall though even without the apps the battery drains quite fast under normal usage conditions. Compared to my S10+ and iPhone 11 Pro the battery is much worse, especially when compared to the latter. It is definitely not a worry-free, all-day phone. The reviews critical of the battery life were spot on. I cannot even imagine the smaller Pixel 4. It probably cannot get through half of one day without a recharge. Reminds me of my BlackBerry Z10.

I've been using my 4XL fairly heavy for the last twenty hours: six hours and one minute SOT, 20% battery remaining, four hours left predicted. I'm having no complaints with this battery. The phone's been in out-of-the-box operating condition, too. I haven't tweaked the phone into a 'Maximum Battery Saving Mode', but I did turn off the "Wop" and "Bong" motion gestures.

I've been running it through the ringer and I really have no complaints so far on the battery.

Really don't know what to tell you. As I said I have the other two phones as direct comparison (I've had the S10+ since launch day, same with the iPhone 11 Pro). For my workload and style of usage - heavy email, medium texting, lots of consumption of reading content throughout the day, news, streaming music about 1-2 hours per day, plus about 30-60 minutes of video on average it is definitely noticeably below the level of the other two phones, especially the iPhone 11 Pro which has kind of crazy-good battery life. I don't turn off any features to "save battery" (never believed in that because I should not need to adapt to the phone). I run auto-brightness, ambient EQ, use the high-refresh display (though not forced to 90Hz), smart stay, blue light filter and switch to dark mode at sunset, etc. Smartwatch (Gear S3) is always in tow. I can get between 4-4.5 hours of screen-on time before the battery is basically out.

I don't know why people are so focused on screen on time as there are so many variables behind it. Could have one person that's just texting all day, social media and some calls while mostly on wi-fi and be like zomg 8+ hours SOT BEAST MODE! Then you have someone that's watching YT videos, doing some gaming, pictures etc and on data the majority of the time but only gets like 4 hours SOT and gets branded as bad. People seem to forget as long as you make it through the day that's what should matter the most.

Spot on and then you'll get someone seeing someone else on 8 hours SOT and wanting to copy their settings to try and get the same result on a completely different usage pattern then complain they can't get it.

Everyone knows the saying "your mileage may vary" but when a majority of people are showing 4.5-5.5 hours SOT, that is disappointing for a phone of this price range. There'll always be exceptions and people getting 6-7 hours consistently but maybe even people only getting 4 hours. That's the YMMV part for this phone. Now for something like the iPhone 11 models, people are consistently getting around 8 hours and even more on a full charge. That's a good 3.5-2.5 hours more SOT. For me I'll be happy with what I used to get the first year or so with my 2 XL which was 6-7 hours and an occasional 8 hour.
It's too soon for me to judge my phone but yes I'll be disappointed if I only get 4.5-5.5 hours but I'll deal with it.

I'm hitting over 7 hour SOTs for the past couple of days and I'm pleased with that. However I also went through each app and restricted background battery usage on every app that I felt wouldn't negativity impact me if imposed it.

this may or may not fit in this thread, but figured i would post it as its battery related
Anyone having issues with idle drain? ... mine seems to be held awake quite a bit, and i cannot figure out why. Same apps as my pixel 3xl, same everything.
Installed gsam, and its essentially saying the system is what is keeping it awake
Was wondering if anyone else had this issue, or is anyone has any ideas as to what may be causing this
Any help would be appreciated

Question Battery life not lasting a day....

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".

Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.

I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.

You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!

SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).

Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.

Is this on the snapdragon or exynos variant?

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.

My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.

Question Battery life and average SOT

Hey guys , I'm near a week with the OnePlus 10 Pro ,Chinese version flashed with NE2215 EU rom ,but I'm not sure if it's only mi idea or my life battery ir worse than average ,I'm using Oxygen OS 13 right now, and coming from an Asus ROG phone 5 with 6000 mAh battery, so I'm not sure if maybe the conversion to NE2215 from NE2210 hasta some relation .
So if you can share your average SOT and detail the model of your phone I will appreciate a lot .

I've already made a thread about SOT, it's difficult to see threads these days seeing as XDA had made forum changes and done away with the long established categories.
My average is 8 hours with a max of 10 hours 41

I actually use gsambattery to get a better realistic screen on time usage for my device.
Android new way of showing you your screen on time is very deceptive in my option.
For me battery life with this device has been ok I get like 4-5 hours screen on time with like 20-15% but I expected better with the larger battery and the LTPO2 screen that they brag about. And this is with AOD off.
