Like most of my fellow XDAers, I've been struggling with battery management issues. What apps to install, CPU hogs and all that jazz.
However, while I've been very pleased with the battery life I was getting from my U8800, I saw several guys complaining of horrible battery performance. I thought that they were just 'doing it wrong'...
I now wonder...
Since November I started noticing strange battery issues. Very fast draining, misleading battery readouts... I wiped my device, flashed it with pretty much all roms (custom and official) available but my battery kept screwing me. And its been worse as time gone by! I now hardly get 8 hours with at most 1 hour of usage.
I'm now posting this after calibrating my battery 4 times the day before and the first time I used our today my battery life went from 100% to 82% in less than 5 minutes! CPU spy reports 85% of deep sleep. Better battery stats has hardly anything logged. I already ordered a new battery but if this keeps going on...
Thoughts?

Why did you calibrate 4 times? How did you calibrate it?
Charge it to full, calibrate battery using app/recovery/deleting batterystats.bin, leave it to totally discharge, fully charge. It is not calibrated until you go through a couple of charge/discharge cycles.
I have very bad battery life since 4.2.2. Trying to understand why that happens. I had around 3.5-4 hours SOT in 13-14 hours total usage which is very fine for me. I don't have very good reception, I know this drains battery but I'm living in same place so reception is still the same. Tried most of the roms and kernels. Flashed everything to stock 4.2.2 manually too but now the most battery life I can see is 2-2.5 hours SOT in 7-8 hours total. This is terrible compared to people at forums. Especially my screen started to eat battery too much, consumes %10 of battery in 25 mins. Even if I don't run nothing, don't use cpu, just kept cpu at 384mhz and screen on to test. I don't know much about these things but started to think 4.2.2 radio may have problem with me. Is that possible? Or what should I do? I will be really appreciate with your comments.
No. It's fine. Update the baseband if you choose to.
I've seen multiple reports from spanish forums of people telling how the battery lasts 2 hours SOT at best since August, me included. I have tried reflashing and wiping everything but nothing works, people seems to have the same issues.
From MTK Engineer mode I get an average of 600-700mA power draw from battery, which is normal at least for me, but battery is lasting much lower. It doesn't feel like a gradual battery degradation, but my phone went from getting 3.5-4h of SoT to 2h at best in just 1 month
So, has anybody experienced the same issue?

I can confirm your feeling, I'm experiencing a performance degradation too. I've passed from 4-4,5h of SoT to 2h in the last two months, I think I'll change the battery soon.
Hey guys,
I'm writing you because I'm new in terms of battery issues for my Nexus 6P..
Right now, my battery is on 63% of its capacity per Accubattery. The good thing is that I'm not having any random reboot or early shutdowns. Even the battery is going down until 8% with no issue. The only problem is that when battery reaches out 30%, it downgrades faster.
I got a new battery this morning, but, I'm not sure if I should wait until my current battery dies to change it.
I'm having 3,5 SOT with my current battery and I'm fine with it.
My concern is: Will I get hardware problems in the future if I wait until my current battery dies or start with early shutdowns?. Should I change my current battery anyway?
In my case, was the same, 3.5 of screen or less, decided change it myself, now generally 5 hours of screen, shutdown at 3% and charges to 93%, is an oem battery, the process of changing is not hard.
The future hardware problem may be relationated with random shutdowns.

Thank you bro, I'll replace my battery then
I replaced my battery not long ago. Day and night difference.
I was getting around 2.5 hours of screen on and now I am getting like 4.5. hours.
Bought this phone 4 days ago on friday. S10plus exynos 128gb, dual sim, but i only use one sim. Android 10 and ONE UI 2.0.
Friday was spent to set up the device. I used smartswitch. Saturday, i fiddled with the device. Battery wasnt that great tbh. Sunday i read some guides and i factory reset it, backuping only messages and photos (contacts are from google). All apps were reinstalled manually.
What got me worried was, i set an alarm for monday at 7.30. When it rang i unplugged the phone and kept snoozing it for another hour. When i finally woke up at 8.30 it was on 94%. 6% from snoozing it?? Come on...
So i reset all three settings (accessibility, network and setting) and cleared cache in recovery mode. Still i was at 6% at 18.00 and i wasnt done with stuff, but i had to go home to recharge... SOT at 6% was 4hrs 50 minutes. I used gmaps navigation for 2hrs and that was the only time i had location turned on.
So today i did some more tweaks and my setup is as follows:
LTE ON all day
Wifi maybe turned on once or twice for few minutes
AOD on tap
Lift to wake OFF
Dolby atmos ON
Sync off
Location off
Bluetooth off
Dark mode ON
Power mode is on Optimized
Adaptive power saving is ON
Adaptive battery is on (altho idk how much it worked in this two days since factory reset)
Bixby is ON and it can be summoned with locked screen
Google assistant is off, but i can "hey, google" when im on home screen.
Screen brightness was most of the time at around 50-60%
Keyboard vibrations ON
Medium resolution
Its 17. 00 right now and im on 10%
SOT is 7hrs 30min but with 9hrs away from charger. I had a day off, so i decided to use it extensively to test the battery.
I have seen peoples results and theyre much better. Like:
-15% left, 21hrs since charged and 7hrs 30min SOT
-15.5hrs from battery, 7hrs sot with 3hrs of youtube and still 10% left
-1day on battery, 7hrs SOT with 2 hrs spent on instagram
-12hrs on battery, 7hrs SOT and 50% left
-7hrs on battery 6hrs 50minutes SOT with 64% left
-the most impressive 1day 12hrs on battery, 13hrs SOT with 4hrs of youtube and 4hours of spotify.
I know it depends on user and his usage, but the results of others are just too much better than mine and i cannot neglect that. And some are using BT, Location and SYNC all day ON with great SOT and standby and come home at night and dont worry about battery. I want it all on too, but mine would probably be dead by 14.00.
I was deciding between S10+ and P30Pro. Huwaei because i know their battery is superb. But samsungs stereo and system convinced me to stay loyal to samsung, and i thought that the battery will be improved and good with a 4100 unit.. But i guess i was wrong. I previously had s7edge and battery wasnt that great either, but i decided not to act on it and somehow got through with it for 3 years with multiple chargers thru the day. I thought this will be a very noticeable upgrade, but its not... And honestly, i dislike night mode and i love AOD always ON, always had it on on 7edge, but im afraid to use AOD and day mode on 10+ cuz of battery. It should be okay from the box for the price it costs. I thought with this big battery i will be able to have Location, BT, Sync, Data Always turned on and get through the day no problem. But apparently not. And I know its possible with huawei and i chose s10+ cuz i thought now it will be possible and i like its UI more.. But well.. Im disappointed..
Can anyone advise me what to do? Is my battery faulty? Should i exchange for a new one? As i said with s7edge i didnt go complain to samsung, but this is second phone with same problem and even more expensive. I feel it should be better. I expected at least 8hrs SOT and to get home at 20.00 (13-14hrs on battery) with still 20-25% left... With most stuff turned on. At least based on this forum and yt tests and what i heard from acquaintances that bought the phone..
I love this phone, its system, features, everything, but idk if im prepared to charge it 2 or more time a day for the next 2-3 years,as i did with s7edge...
Ps: in 16minutes to finish this post it dropped from 10% to 6% already on medium power saving mode...
Thank you for any help
Also those 4hrs of Samsung Internet were 95% news and forums, basically just text and no videos.
Also idk why the new android 10 battery usage doesnt show Android System and Idle. But here is also screenshot of Android system and CPU spy
Disable AOD service for amazing battery life
I disabled the AOD service and my battery life has doubled with Android 10
Your SOT is very good. 7hrs is quite impressive. I'm getting 3-4hrs SOT and mostly I'm losing 15-20% per night. But I have this Standby-Usage since my first Samsung (Galaxy S Advance) and I accepted it as normal.
Yeah today SOT was okay. But you gotta count in the battery since charge time. Yesterday my battery since charge was 12 and half hours. And my sot was 4hrs 50 minutes.
So i guess today would be the same had i not used the phone constantly.
I just dont understand how someone has a phone more than 20hrs since charging with 7, 8 or more hours of SOT. Yet i dont. Same phone..
And yeah i know AOD drains, but still theres sth wrong when your battery doubles if u turn it off. And with 4100, battery unit and 900€ phone this shouldnt be a problem.. Seriously thinking about exchanging it for p30pro. No need to tweak it and it battery just lasts. Ahhhh -.-

I would say your battery life is good..I have Exonys version and I have most of the same settings on that you have on, plus some extra ones...before I installed android 10 I used to get +-12-18 hours standby and a sot of +- 2-4 hours depending on how I used my phone. I never switch off my phone(standby for work). So, when I go to bed the phone just lies there from 10pm till 5 in the morning.... I will restart my phone once a week. AOD is on from 5 in the morning till 8 at night. I never use any power saving modes. The best sot I ever got was 5h54...and the battery lasted 12 hours and most of the sot was playing candy crush...
With Android 10 the sot is still basically the same, but the standby time(idling/sleep) is much better....I get 18-24 hours now, depending on usage.
I know the snapdragon has a better "battery life" then exonys version. In general the battery life isn't the best, but also not the worst compared to other top brands...I had the S9+ and the battery life was worse then the S10+...I get +- 8-12 hours more life out of the S10+

Forgot to mention that when the phone sleeps, I loose .5 % per hour.with aod I loose 1-2 % per hour. When fully charged the first couple of percent drops quickly, but drops slower after 90%. I Have VOLTE and VOWIFI on permanently, I just switch off wifi and data when I go to bed, so for 18 hours a day I'm connected to wifi from home and work...when travelling I have a hotspot in my vehicle. Data connection(LTE) does eat more battery, but some areas our signal is very low and that eats even more battery...Over the weekend I streamed music to my bluetooth speaker for 10 hours and I lost +- 20%....that's including a lot of screen unlocking/locking, checking whatsapp etc.. Was very impressed..
Well thats comforting to hear.. Does it not bother you that some are getting much much more? Like crazy more..? Those examples of high standby time and high SOT are all from Exynos version that i found in the battery thread her on xda
It did bother me when I got the phone and tried all the tricks for better life and still I couldn't get close. The battery optimization took a while to "learn". Battery life is getting better slowly but surely...A longer battery life would be nice, but as long as I can get through a full day I'm happy. There is some days where I get through on the battery with some 40% left...other days I get home with 15%...usage per person and cell reception is a big factor for good battery life
Ahhh i just get real jelly seeing all others with such good results and i dont understand how it varies SO MUCH from one person/phone to another. Seems like a lottery.
I get even more jelly when i see p30pro results its consistent and same for majority of them and its soooo much better... But their system and features to me arent as good as samsungs.. Cant they just make a phone with samsung features and systems and huaweis battery? Hahah
lol...One of my friend has the p30pro and in the beginning the battery was great...He had it from the beginning....now, some time later he has worse battery life then me...
Seriously?? What messed it up for him? Maybe an update, faulty battery, or does this happen to all huwaeis?
My brother has a two year old huwaei and his battery is still amazing..
Same thing to me. Inconsistent battery, one day is good, one day is bad. I am pretty dissapointed, but I do not want a Huawei again. Features from Samsung are clearly better, and to pay 1300 eur to get an iPhone with 512 cause 128 are not enough and they do not support sd card... not worth. So, I will stick with Samsung, use my external battery sometimes but to be honest, it was more than enough how it lasted for me, it is just that obsession to have a good battery like everyone else.
If I am at work I have some wireless charger but I still do not use it cause I am busy, if i am at home i can charge it anytime... so there is no need to bother. I learned to not be that obsessed anymore and enjoy my phone.
What's wrong with 71/2 hours? I don't get anywhere near that?

My friend's not sure what is causing the problem, but he barely makes it through a work day....He bought himself a car charger and charges it on his way home, the trip takes about an hour per day....as he won't make it on a single charge for a day...He leaves work at 5 in the morning, takes the phone of charged and by 5 he has to charge again

7.5 with low standby time. With this standby time, according to others should be much much more. That similar to what i got on s7edge with smaller battery.
I unplugged today at 8.50. Its 10.26 and im on 82%. With hour SOT. With a bit youtube and some forums.. Thats just unacceptable..

Exactly. This dont get thru the work day either like some people do..bought this phone cuz is saw people get great SOT and they get home late at night with still battery left... And thats not what i get with mine.. Srsly dont get it...
Since you had your phone only for 4+ days I wouldn't stress too much...It took my phone 2 weeks to "learn" my patterns and optimize the battery accordingly when I was it was running Pie. When I installed Android 10, in the beginning it was crap, but 10 days later the battery was optimized...I make sure that the minimal apps run in the background/most are sleeping...
---------- Post added at 04:44 AM ---------- Previous post was at 04:43 AM ----------
The battery was very crap in the beginning, but got better over time
Thanks for reassuring me. Im stressing so much cuz i got a week to replace it if its faulty. The deadline is on saturday.
If i miss it i can only use the warranty. Which is fine, but the seller or samsung has more rights and can make you wait for up to 40days to find your phone.
Within the first 8days you have full right to demand new device or your money back. At least thats consumer law in my country.
I did the warranty fiasco with s7edge cuz it had faulty screen... Never again. Costumer service terrible..
Followed corv0s guide..still not even close to 8-9hrs SOT... This battery is awful and idk how, since its 4100 unit. Not happy.. Today is last day i can still demand new phone or another phone..
