Battery usage reporting 10% intervals - Defy General

Hi guys,
I'm noticing that, regardless of what tool I use to check the battery level, it only reports in 10% intervals. Ie it goes from 80% to 70% to 60% etc.
Does anyone know of a way to fix this? Running the stock ROM on my Defy.

Your actually lying once its down below 20% it goes in 5% increments.... and no fix its a hardware thing im pretty sure.

It's not hardware limitation but AFAIK it's a kernel "issue". We need a way to modify the kernel so we can have more graduation in the %.
On my old phone it was the same 10 to 10% but with some custom ROM with custom Kernel we had 1 to 1%

Heh lying is a strong word.. I just never had it drained below 20% so never realised it did 5% increments after that point.

Oh bugger. With a locked bootloader on the Defy preventing us from running custom kernels.. looks like this is an issue I'll have to live with. Dammit.

[Q] High battery drain because of Android-System

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Yes, i think your prob comes to every Android phone after flashing New rom.
Just wipe Battery stets after flashing. It needs few complete chargings to calibrate the battery.
There are also many apps in the market for this

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.
I had a LG Optimus Black before and didn't last a day. I'm loving this Galaxy Nexus.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?

Which ROM for best battery?

I'm currently using MildWild 4.3 Final and find the battery level decreases on idle far too quick. I've checked using badassbattery app and nothing untoward is shown in there. Any advice would be greatly appreciated

firstly, need to know what your actual decrease over a period of time, and whether you have anything syncing. and also what you're expecting or wanting it to be. this can be very subjective. what you're already achieving could be quite good. age of your battery is also important.
- assuming you're using inbuilt kernel, set min cpu to 245 ondemand
- betterbattery stats is another useful app to check partial wakelocks (bad apps keeping phone awake)
- use something like currentwidget to monitor idle battery drain if you want to. with screen off, 3g on, the minimum standby drain you can normally achieve is around 3-5mA drain.
if the above checks out, it's probably not a rom issue, may just need a new battery. switching roms may make a difference, and you can try the above on others to actually measure if there are any, rather than placebo. oxygen is supposed to be of the more efficient variety anyway
I've done all those things and I'm also using a brand new genuine HTC Desire battery. I still find that when I leave my phone alone, no Wireless or data or any app running in the background, the battery goes down by 10% every hour or so.
woah then that's way too much, definitely doesn't look like rom/sofware issue to me, sounds like hardware.
what does idle battery drain report?.
i think there are other apps which will measure the actual battery capacity. if it's official should hopefully be close 90-90% of the stated 1400mAh capacity i believe.
not sure what else to suggest which will actually solve problem this however, other than repair

ManU is not designed for oxygen, also loses camera drivers by doing this. 2% idle drain / hour is not that great either...50 hours standby with screen and wifi off...
@elrasho, you could try flashing a different rom or stock RUU to be absolutely sure. if you've done all the sensible things above like checking bad apps and still getting ~10% drain / hour, you can pretty safely assume it's hardware...

2% an hour is so efficient! You find another ROM/Kernel which can give you the same battery drainage.

stock/inbuilt kernel with ondemand should work just fine. mod 8 is based on slightly older sources. whether smartassV2 is better depends, but i think it has to be actually measured, not 'seems to last longer'
The older kernels tend to be more power efficient ala manu kernels. I've never tried leaving my phone on standby and waiting for it to discharge. I get 14 hours out of my desire a day with mw cm 4.3 with manu 2.1 cfs kernel under moderate to heavy usage

not tried enough, though i trust bortak!
but no rom should give you 10% / hour idle drain...stock rom/RUU with nothing installed is an easy benchmark to test
i still think it's hardware by the sounds of things, but doesnt hurt to try other roms in the meantime. hope you work something out:fingers-crossed:

Jelly Bean Draining Battery

Hey,
I recently unlocked my bootloader, rooted, and installed CM10 on my HOX. I did a full battery drain and then full recharge before using, and still noticed that my batter is still being drained at a worrying rate. (3 hours gone and just 57% battery left) The screen takes 52%, but the Android OS takes 21% and the Android System takes 5%
Is there anyway I can reduce this battery drain? I understand the ROM is still in Alpha, but I've heard people still achieving 3 hours screen time with it! Maybe something to do with getting a new efficient kernel ? (I'm still new to all this).
Many thanks in advance

hi there - just a thought of sharing with you since you've already rooted your phone -
- Domination ROM CM10 thanks to Owain94 check it out on the forum http://forum.xda-developers.com/showthread.php?t=1799375
- NCX 0.99bOC kernel by n3ocort3x see comparison here done by nimrodity (thank you guys) http://androidroots.com/king-of-kernels-kernel-comparison-htc-one-x/
Again it's a custom ROM expect for some bugs to come up - but you decide at the end since this version are better than alpha

[Q] Cyanogenmod 10 battery life on normal usage.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?
Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.
Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?
I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...
You have problems with motherboard. Go to service center to replace it on waranty.

But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!
Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.

How long does yours battery last with some normal usage?
Almost 3 days with moderate usage.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.
Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!
