[Q] Performance Lacking After Root - HTC One Max

I've been stock rooted for several weeks now & have noticed that the phone isn't quite as fast as it was stock. It's not as responsive at times & even worse I've noticed the battery life has decreased. Before I rooted I could easily get a solid 12 hours & now I get 8 to 10. Last night I went to sleep & my phone was at 72% & when I woke up today it was at 12 which is horrible standby time.
This is the 3rd HTC I've rooted & I've never had an issue like this before. I haven't had a chance to go S-Off yet. Any idea on what it could be? Any suggestions on what I could do to improve the performance back to what it was?

Any help or suggestions would be much appreciated.

I'm not sure from what you have said what the cause is. I just know that I have used all of the different roms for this phone (I'm on Verizon) and never had any battery drain like that. Maybe a factory reset and watch what 3rd party apps you re-install? One (or more) may be causing the drain.

[Q] Another battery thread whith a diffrent approach.

Im starting this thread because of every battery thread I've read people NEVER seem to solve the problem unless they replace their ATRIX. Now a few questions. This is directed to any ATRIX owner in an attempt to find a solid solution.
1. Did your ATRIX only start having battery issues after upgrading to gingerbread?ATRIX or have you had issues beginning from stock froyo?
2. Has any solution suggested by anyone ever worked for you?
3. Does your ATRIX get hot and battery drains extremely fast?
4. Are you frequently connected to 4g H+?
If you answer no. To #2 and yes to #3 I suspect it may be a hardware problem...
on the battery this is what I see and find strange and this is the battery that came with the phone.
1880mah
1880/1930
Mah(min/typ)
7.0/7.1
Wh(min/typ)
Idk where to find production number so I guessed its this [GB/T 18287]
On the phone idk the specific so I took a guess too XD [SKU:65230]
if someone knows the two above please correct me but anyways I posted those because we can compare for those that have a problem and maybe pinpoint it to be a factory defect. Again I am doing this because this battery AND heating issue is aggravating and after 2 months I can't stand it anymore no fixes ever worked so help me and those with the issue out by providing information thanks.
Hello,
1-Yes
2-Not really, I have increase the battery life but not good as the stock Froyo.
3-Yes, but as I remember it get hot too on Froyo. Less or more... I don't know.
4-Always
I have buy an Andida 2200mAh battery and use it since 3 week, I will return to the stock battery tomorrow to check if there is a difference.
1- Nope, my battery has always lasted for around 8-10 hours everyday. (I play games and browse the internet everyday).
2-Never had any battery problem so....
3-Not at all. My Atrix has always been cool.
4. for about 4-5 hours a day (usually i am on wifi but wifi or not.....i have the same battery life).
It could be a ROM problem that you are having, maybe doing a clean install of a ROM could help you(do a complete wipe before installing the ROM). Are you using faux 123's kernel? It under-clocks your Atrix to as low as 216 GHz when your handset is idle but overclocks it to 1.1 GHz when it use. You could download setcpu to under-clock it for better battery saving and this will make your phone less hot.
You can and should also download a battery app from the market and see what your battery temp is like compared to other users. If it's a hardware issue indeed, you better return your Atrix and get a new one asap as it could cause you harm in the future.

That's just it with everything stock gingerbread my friends ATRIX doesn't heat up as hot and eat through batteries like a fat guy an a dozen doughnuts in one sitting. We both had stock when I tried this his phone easily outlasts mine both on 4g and a factory reset I tested this when he asked me to root his phone I was gunna kill its bat and charge it to root and install unlock etc. And to my surprise holy sh#t his battery life WAY outlasted mine, AND HIS DEVICE IS ONE.MONTH OLDER i've had this ATRIX for 2 months now so its none of whatever everyone is saying about battery caliBS its a firm suspicion on a hardware flaw, the sooner people can find it the sooner Motorola can replace defective handsets, ridiculous, two stock gingerbread motorolas with 100% stock and mine only lasts about had as
long as my friends own who gets battery results everyone brags about.
i own 3 atrixes ive had an atrix since launch day had its issues at first but one thing that was never a problem was the battery it was always amazing lasted 2 days sometimes well since the offical ota uPdate i updated only one that way its my main phone and right away i noticed the heat coming from the metal clip holding the sd card then next i noticed the batt life was losing 10 every 20 mins or so. since i have rooted it just so i could try n use tb to freeze all the bloatware and still nothing then i tryed just bout every other method on this forum so i didnt wanna lose my warrenty on that 1 so i didnt unlock it so i took my other atrix with a slightly cracked screen it was running on 4.1.26 so i rooted it unlocked it and charged too 100 then flashed to alien v3 so wen it was done it upgraded to gb and right away i noticed the heat from it just like my other one and battery life was losing 10% every 20 mins just like my other one i have also tryed everything on this forum im lost now dnt no wat to do somebody please help also as upset i am about this happing im very relieved to c im not the only person with this issue

Horrible battery life after 2.3.6

You have an app that is driving data to your phone, causing the wifi chip to wake the phone all the time. Apparently a system app - a lot of people have been having this issue with KK6.
Beyond this - sorry, but if you are not rooted you will have to live with it. Identifying what is triggering the wifi interrupts requires obtaining a Wireshark capture, this is not possible without root. Even if a common root cause is found for what's going on with KK6, it's most likely in /system itself so can't be fixed without a custom ROM or at least rooting.
If you're not willing to root, why are you on a firmware developer forum? Have AT&T help you instead if you're on 100% bone stock unrooted.
Well if it's an APP causing it, then many many people must be running the same app cause all of the various forums out there are a lot of people with the battery drain after updating to 2.3.6. Even a lot of my customers have mentioned it also.
I doubt it is an APP doing it. I'd bet it is just some bad coding on Samsung's part. They are probably getting a lot of complaints and are most likely already looking into it.
As far as the why he is here if he doesn't root. Well I don't root as well and have no desire to being as stock works just great. (other than the battery drain)
This is a great place to hang out and keep up on other people using various phones. He posted in the General section, not the Developer's section for this phone. So I think his/her question was valid.
If he was asking the question in the Developers section I would understand your concern. But I don't feel you have to be into cooked ROMS to value this forum.
That's like saying to the people who like the "Fast and the Furious" moves to stop watching them because they have a Chevy and not a pimped up Civic.

I'm not rooted with wifi on all the time just got the phone 3 days ago and I'm getting 14-15hrs with no issue down to about 15-20% battery life left before I have to stick back on charger. Could be a bad battery or device, I'm coming over from Sprint after using rooted evo3d and rooted photon.

The forum is called xda-DEVELOPERS.com
If you don't want to root, you're probably better off in the AT&T support forums, because honestly, it isn't worth our time to try and help someone who doesn't want to root fix a problem that is almost sure to require root access to fix, or in this case, even diagnose.
I do believe many are having this issue after upgrading to kk6 (with same apps installed). I had the issue as well.
May be a system app, or something in /system causing an app to become unhappy.
Either way, it's not going to get fixed without Shark for Root captures from those encountering problems.

I don't think it anything to do with KK6. As Entropy said its an app causing a wake lock. I'm run Ingram KK6 without any issues with battery.

Having this issue as well. Phone is stock. Ive been here since the captivate but I hang around with the sgs2. Never needed to root this phone as it works perfectly for me. But I did the update this morning at 100% charge and 9 hours later with no use it's down to 9%. I could go all day with moderate use and be at 30-40% by the time I go to bed.
I read on a rather long on a google forum that many had this issue after upgrading via ota but who knows. I found that wiping dalvik and flashing unnamed update again I have much better batter life. I did read in update that he reverted to an earlier kernel signature to fix the battery drain.
Im going back to 2.3.4 via this method.
http://galaxys2root.com/att-galaxy-s2/how-to-unroot-att-galaxy-s2-sgh-i777/
Losing 10% of my battery at idle /hour is ridiculous lol. Android os was at 87+% within 3 hours of restart.
Edit:
Okay so I did this method. Took about 5 mins after I got everything downloaded. I did not do the factory reset since it's not needed. Phones back to 2.3.4 and nothing was reset. Have all my sms's contacts, aps, wallpapers etc. Battery seems to be back to normal.
I recommend everyone who did that 2.3.6 update to revert back. To many problems with it.
I never entered download mode on this phone before. Just a tip: Keep holding all the buttons till the phone seems like it shuts off and keep holding them till you get into download mode. Do not let go or else it just powers off.
For the purposes of attempting to fix the problem, I really would like some people to take some Shark for Root captures as described in my Known Battery Drainers thread.
With that data, the root cause of the problem might be identifiable.
So far I've only seen one capture, I really need more unless I can reproduce the problem myself.

I read a possible solution on another forum and tried it with my SGS2 today and am amazed at the difference today in my battery life.
Worth a shot as it does not require anything more than charging your phone and pulling the battery.
Charge your phone to 100% with the phone off (hold the power button for 3 seconds or so until the menu comes up and select power off). When you reach 100%, unplug the charger and remove your battery (some said keep the battery removed for 90 seconds while others said 3-5 minutes). I left my battery out for 5 minutes or so. Put the battery back in and power on.
That was it. My Android OS went back to normal and the battery life today has been great if not better then with 2.3.6 than before I updated.
Screen grab of my current battery use after trying this method this morning is attached.

Quite possible, but still running on the same charge from this morning and am at 28% battery after 14+ hours of normal use which is all I expect (calls, texts and light web browsing during the day over data) and then couple hours of web use at night over Wi-Fi when at home.
The last few days I was charging the phone when I got home from the office if I wanted to use it at night. Android OS was way up in the 60+ range after I first updated OTA and today it has been under 20% and more near 15%, so I'll take it.
---------- Post added at 11:09 PM ---------- Previous post was at 10:59 PM ----------
Come to think, I probably did not do a reboot after the update and could have been all that was needed.

I did this and saw absolutely no change. 2.3.6 is draining my battery far faster than 2.3.4 ever did. The culprit is the Android OS running at 90%.
I read that it might be an issue with the wifi so I have turned that off and will report back if that seems to fix it.
I read on another forum that att and Samsung are trying to blame it on bad batteries and shipping out new batteries.
What a bunch of crap. People everywhere wouldn't suddenly all have bad batteries at the same time. Sounds like usual BS.
I personally think its just some bad coding that Samsung needs to figure out.
On a different note, I played with the Verizon Droid Razr yesterday. Man that is a really nice phone. I'm tempted to get it, but I work for att and get free cell service, so it wouldn't make sense to pay for Verizon service, even though I think their network is better.

Android OS is definately eating up the battery now. I think it does have to do with wifi, because it seems to be much improved with it off. I'll take a free battery as long as I don't need to exchange the old one.

SGS2 ICS battery life

After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers

[Q] Terrible battery life

Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

Yeh...thats nearly double the battery drain i'm seeing.....
I really think you should either re-flash the stock build using samfirmware.com, or flash up a custom rom you can adjust to get this battery issue under control...g

Agh, yeah I'll have to give that a shot... Been looking at CM10 or something, I had a jailbroken iPhone4 previously so I'm not ADVERSE to doing this... was hoping to stay stock a little bit longer... I know the samfirmware thing is the stock firmware but still, playing with the OS DOES cause a bit of anxiety...

Though, would a factory reset take it back to GB and allow me to do the upgrade again?

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Well, yeah screen destroys the battery. After ICS it seems as though they cranked up the brightness and contrast. Or is that just me?

[Q] 1) Upgraded from 2.3.3 to 4.1.2 by Samsung. 2) Battery hates me. 3) :( :( :(

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

Cyanogenmod roms are very fast ROM they are good as hell
Ur problem is genuine go to the playstore and download battery calibration app and follow the instructions in the app charge or battery up to 100 % and caliberate the battery u should have made an nandroid backup before upgrading

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.
