Battery drain in standby issue?

Hi all,
My 6 days old Sensation (Vodafone contract UK) discharge a huge amount during Standby (200-350mA). I got the number via Battery Widget Pro 1.65. For the first few days I did deplete the battery fully before charging it to full. Today I have factory reset it to the original condition at around 4pm with 58% battery full. Now at 9pm, it is only 18%. During this time, I spent about 1 hour with the phone, the rest is standby. I set the widget to monitor with 1 minute interval and when looking at the log file, it can be seen that the phone consumed from 200-400mA during the standby time. Coming from HD2 with Android modded 3-8mA standby consumption, this is a huge huge dissapoinment!
Is this because of my battery or is this my phone? Should I ask for a replacement? What about you, did you see similar pattern?
Thanks,
Duong

Ditto!! So annoyed since I too am coming from HD2 where HyperDroid's consumption had dropped to a flat 2mA in standby. This is insane for a native android device. Not to mention the heating while playing games and most importantly, the front facing camera producing upside down image during fring video chats.. grrr!
Dunno what the cause OR solution is (besides switching over to a custom rom if and when the BL gets unlocked and people like pongster develop for this device)...
Overall, sexy device but disappointed with such major holes left unattended..

A little offtopic but was a battery related questions and did not wanna start a new thread so posting here -
Does anybody know of if there's any app which can get the battery percent to show in the top bar instead of the default indicator?
Thanks
EDIT: neva mind... found it... everybody's allwoed 1 dumb post once in a while

something is keeping your phone awake, you need to figure out what it is.

Any ideas on how I can do that? I tried using current widget but I guess because it's not rooted, current widget showed me a log of 0mA all throughout (yeah rite! hehe)

when I figure it out myself I'll let you know.
Current things I found that killed my battery over night: VTOK & Google Latitude

I went into Settings --> About Phone --> Battery --> Battery Use and checked, and it says display is eating most of my battery.
As far as mine, I get about 12 hours of battery life with standard usage, with the display eating most of the life, so if you're saying the screen is off, you might get different results...

over my 8h sleep battery dropped like 10%, nothing special (count in : wifi on, sync with gmail, weather) guys. new phone, fresh unoptimized kernel and radio. it'll get better. my prev phone (desire) was like sh*t at beginning in relating to its current spec rom ... and btw for checkin consuption : system panel (not lite), there is monitoring and u can see which apps running again if ya shoot them, check sync-s etc. many many thing to do, hard to tell in a single post

well it certainly sounds like a part of it is specimen issue.. here's my latest experience... last few times i have let it completely discharge and then charge back while the phone was off so i dont mess with it... once 100% charged, i switched the phone on and received a call.. a 25 minute conversation ate away 15% of my battery... LOL...
then, (now it gets better)... in 2 hrs of standby, the phone was at 60% which means it lost another 15% battery in 2 hrs of "standby".. im not sure if i can even call that state a "standby" anymore...
anyways... im wondering if its worth pinning hopes on rom development on our forum or should i just return this and go with something like nexus S which, O well, I can live with... atleast it has a 3300mA batterypack available... what's the use of kickass speeds and features if i have to use a phone like a desktop..

Hey, I have pretty bad battery drain during stand by as well I recommend trying to adjust the sync accounts, esp HTC hub and how often it updates that should improve it...I have a bunch of HTC widgets set up so im suspecting that being the reason for battery drain during stand by also adjust your email update setting accordingly. Every little bit helps!

Battery gauge stuck at 100%
Another one slightly off topic - but why start another battery thread.
It is the second day with my Sensation, and since I took the phone off the charger this morning, the battery gauge has been stuck at 100%. All other apps reading the battery status (e.g. Battery Widget) show the same number. I rebooted the phone multiple times, replaced the battery - nothing - permanent 100%. Has anyone had a similar experience? Did I get a perpetuum mobile ?
BTW the readings were fine yesterday.

Yes, the rating will go downhill pretty quick after that. Mine behaves in the same way.

Thanks for the pointer.. I will surely try that and see if it makes a difference..
That being said, call me crazy but it just occurs to me that HTC should be putting in some minimal efforts to check off basic quirks like battery consumption and QC. I mean all of us are spending a buttload of money on these devices year over year and then we rely on our devs here to give us basic functionality. Back in the days the reason people joined forums was to tweak devices.. Now it almost feels like we might as well expect only the hardware for the price we pay... disappointed!
Anywho...

I fully charged the phone before I went to bed last night. Eight hours later, the battery is at 10%. Is there something wrong with the battery?

Try using the Spare Parts app to see what's really using the battery in detail.

[Q] Why is my standby battery usage high?

Hi, I have just come over from the HD2 threads as I'm using a Sensation XE now . My battery current when running android on standby was around 7 - 20 ma. On my XE it is between 180 and 220ma. I killed all running tasks etc but still no change. i'm using Battery Monitor Widget to check the currents. The only thing i have on is mobile internet. I also have on background sync but that was on with my HD2 as well. Is there anything I should look out for that my being draining the battery? Also I'm on stock rom

What did you already tried to solve the problem? Did you already do a soft reset/wipe all data (except that on the SD card)? How long is your battery life?
Yesterday i called HTC because my battery life is reduced drastically compared to a few weeks ago. They told me to turn off everything like bluetooth, wifi etc (after a soft reset) and put the phone in plane mode while screen brightness was 100% and screen time out never so the screen stays on during the test. Next I needed to write down how fast the battery was drained. My battery was at 55% after 2 hours (without doing anything with the phone). According to HTC this was to fast and therefore they send me a new battery.

In 1 hour of standby the battery has drained 5%. the battery current usage is way to high for standby. I have had this phone on 3 days so I dont think i need to do a full wipe. I dont use wifi or bluetooth and they are always switched off. Seems strange to have a high battery usage while in standby compared to my hd2. This battery is meant to be a high capicity

use battery monitor widget (use a beta version from the forum, not the market). set it to "mA corrections" and choose automatic from the list of supported phones. i get anywhere from 5-7 mA drain (standby, of course).

Try turning OFF mobile data AND sync. Then see how the standby current drain is.

Hi indie.
How is your battery drain now? I ask because I have same problem (original rom) and I don't know what to do.

Hi, I'm on stock Rom too. Once I kill all tasks by the default task manager, it ranges between 25 - 60. It does take a bit of time to get there. I Have seen it as low as 19. You need to follow steps and get the beta widget and set it to corrections as mentioned earlier in the posts.

Same here, took about half an hour to go from ~-100mA to -30mA
However I can't seem to get 0mA when fully charged. Anyone else with the same issue?

Check out guide in my singature.. It will solve your battery problems in no worires

Just a quick update. I let my battery completely die (never done this before) and charged my phone fully. I then deleted the battery stats.txt and switched phone off. the charged some more. Now when my phone uses -5 on standby which it never did before.

Well took my phone off charge at 11.05 today and its been on standby. It's now 15.52 and battery is still on F. Battery drain is now at -3 so i'm well happy.

Thanks indie. Can you let us know what will be happening in the future with your battery?

Guess, I get to ask for help. [Ticket Closed for Now]

Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.

on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?
http://forum.xda-developers.com/showthread.php?t=1450962
kernel: http://goo.gl/ZqBZl
btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha

Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search

Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

I was on battery for around 13 hours yesterday with wifi on for at least 8 hours of that and plugged my phone in with 51% battery remaining.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues

fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms

I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.

Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

Thanks again. I'll definitely try the wifix along with the rest of your suggestions that apply

I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.

I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.

I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:

How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer

Think mine is clearly a battery issue. Replaced the battery with a new one yesterday and now the phone lasts 6 hrs at least on a single charge.

CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.

Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.

Nexus 5 battery drain - new battery, new ROM, still persists

My beloved red Nexus 5 starts acting up... the battery drains extremely fast. Some weeks ago, I could barely make it to 2pm without having to recharge after unplugging. So I got a new battery (directly from LG, so definitely a genuine part) which improved the situation, but didn't completely solve the problem. Additionally, I flashed a CM 13 CAF ROM (using myfluxi's kernel) onto the N5 - I enjoy it so far, but there was actually no further change converning battery life.
Right now, the phone is at 10% after being unplugged in the morning at 9am. Wifi, bluetooth, GPS and mobile data were constantly on, cell signal was mostly perfect, wifi was connected for about 3h, bluetooth was always connected to my Moto 360. Screen on-time is about 2h and I listened to music using GPM for about 2h. The battery settings do not indicate any app using up too much battery power - it shows the display at 15%, cell standby at 10% and then several apps.
What do you think - a Nexus 5 with a new battery should make it through a day, shouldn't it?
I remember my first Nexus 5, back in the days with a G watch, making it through a day without any problem with 15-20% left when I plugged it in before going to bed... because of that, I start to think if there might be a bad electronics part, like the display backlight or something on the mainboard, using up too much power without being noticed by the OS. Is that possible?
Thank you very much for your advice!

Read and post in the battery life troubleshooting thread stickied to the top of this forum, it will help logically determine what is using your battery.
You have a lot running at once, so difficult at the moment to solve your issue. It's better to turn things on/off one by one to make logical conclusions whether it has any noticeable effect.
The best logical way to conclude if it is a hardware problem is to go fully sock no additional apps no root etc, see if it 'drains' by itself
If not hardware, then 99% of the time it is a bad app(s) keeping your phone awake

This is likely not the case, but have you checked the CPU settings? I've only encountered such a drain while using performance governor together with overclocking.

Same here
I have the same problem and I have been banging my head about it, I don't really use my phone for anything much else than a phone and I kept having at least 3 days of using it with no problems.
Now the phone barely lasts 2 days and even switches off in the middle of the night...

In the OP's case, his drain is likely caused by having GPS on all the time. That will absolutely devour battery life, so he could save himself some grief by turning it off until he than your phone turns off occasionally. First guess would be the power button going bad; that is generally the reason for needs it.
For you, who knows? You've not given any information, otherthat type of behavior

Yes, sorry about that I was a bit annoyed at the phone. I found and fixed the problem. Go to settings > apps > disable google fit > click yes when it gives you some notifications about how you'll lose data or stuff like that > and click force stop at the end for good measure.
I am in my second day now of battery life at 59% with a looooooooot of talking today , I mean more than usual so it is definitely a fix for me. Hope it helps
Take care gents

Again same problem
Hi all,
Unfortunately I have better battery life but I am again losing a lot of battery.
I have a screenshot but I am unable to upload it sorry about that.
I use my phone mainly for calls roughly about 15 mins per day at the most in total ( not a lot at all I know) and I also have my bluetooth on at all times cause I have LG G Watch.
thing is that I have never had problems with the battery before. When I say before back in the day I still had my LG G Watch ( I have it for about 6-7 months) . Problem with the battery started roughly around 1 month.
Location is off, wi-fi is on on very rare occasions throughout the day when I need to check my e-mail and mobile data is the same. Navigation is used only if needed.
The real problem is that before I knew what was draining my batter now I have 79% of battery usage and I have 5 apps listed that drained each 1%
Android System 1%
Phone Idle 1%
Screen 1%
Google play services 1%
Android OS 1%
Where are the other 15 % ??
It is weird I really took pride in that phone and his battery life, I know that it is mainly because I don't use it as a regular used do i.e. gaming, facebook etc, but I still want to charge less than 1 time per 2 days or less
Thanks in advance
Regards
Nik
