Fix for poor battery life on dj05/dl09 (rooted)

Hi all I did this last night and it worked wonders on my battery. Before this with screen brightness at about 20% and 10 hours of being on the battery would be dead. The screen on time was 3h15m at best before it would die. After I did this I tested my battery by playing a movie, games, web and texting. When I put my phone on the charger last night screen on time was 5h flat. I was amazed. So I thought I'd type this up for anyone with battery woes. You need to be rooted and Clockwork installed.
1. Dial *22899 and let it do its thing. This helped my battery drain while in standby. Now drains about 1% every 3 hours of standby.
2. Charge phone to 100% (phone on)
3. When the charge hits 100% power down the phone
4. A green battery will show on screen and show its not fully charged. Leave it on the charger until it shows 100% (phone will vibrate to let you know and state 100%, do not unplug phone)
5. Once it reaches 100% boot into recovery by holding both volume keys and power until the Samsung logo appears.
6. Choose "apply update.zip" (use the home key for selection)
7. You are now in Clockwork. Use the volume keys to navigate to "advanced" and the back softkey to select it.
8. In the advanced menu select "wipe battery stats" (there will be no conformation)
9. Back in the advanced menu select "wipe dalvik cache"
10. Now back into the main menu and select 'wipe cache"
11. Select "reboot phone" and wait for it to reboot (will take longer than normal)
12. Once fully loaded unplug the charger and run the phone until the 5% warning then plug back in

So, it sounds like this battery issue only affected those that were rooted to begin with and had to manually clear thiese caches?
I have not noticed any different (good or bad) with my battery on stock only builds DI01 to DL09.

Yea mine kinda went south after I flashed Dj05 awhile back. Alot of users are reporting worse battery after DL09 too though so I thought this may also apply to them.

Battery life is also affected by your kernel and rom combo. Adyrnalyne's kernels seem to have awesome battery life. I last charged my phone saturday night and it's just now dropped down to 17%. However I also did a full wipe including battery stats and davlik when I installed superclean and this kernel.

Yea Ad's were best for me too im on Blackhole 2.4 and Ad's 12/30

Did not work for me
I tried doing this multiple times and it did not work for me. After updating to DJ05 I started to have problems with my battery draining extremely fast (about 3x faster than on DI01). So I upgraded to DL09 thinking it might fix the problem, but it did not. What did work is draining the battery down to 0% and the phone shut off. Then I plugged the phone in and held the volume up/down keys and power button to get in to recovery. I then applied the update.zip to get in to clockwork recovery and scrolled down to the advanced menu and wiped the battery stats. When I rebooted the phone the battery drain was better than when I was on DI01. Not sure if this will work for anyone else but it worked for me.

Yeah, wiping the battery stats when making any major changes seems to help a lot.

I did that too and it didnt help until I wiped battery stats AND cache

Typically I always charge to 100% with the phone off then wipe stats whenever I install a new rom. Was curious why my standby was killing battery on DJ09 and not DJ05, so that *22899 reset helped a bunch.
I went from around 68% no signal from standby to 28% in the short time I've tested.

gonna try this. I was on DL09 for awhile but battery sucked. went back to DI01 but couldn't handle the GPS issue. Going to try this and see if it fixes my issues w/ DL09 and battery.

this worked for me... I has previously just tried wiping battery stats to see if the battery life would improve. I had also changed kernels and switched to dj09 modem so I want sure who the culprit was. I also tried another corrective step by letting the batery drain to zero then turning off and charging to 100% before wiping batt stats but that didn't work either. I am back to normal now which was already pretty good. I should have never messed with the settings in the first place but was curious

so you did the drain then wiped battery status?

I can't believe I didn't know this before. Huge difference. My method was pretty much like the first post. Totally drained battery, dialed the reset number, charged phone to 100% while off, unplugged and replugged until fully charged, wiped battery stats and caches, and I'm still draining. At 43% after 19 hours of lighter use.

Not sure if *22899 fixed my battery issue, but I have now been at 91% after 1 1/2 hour WITH wifi enabled! I've received a few emails only. Not really been messing with the phone. Seems to be alot better then the first time I had DL09.
jv
After a few downloads, a few google talk sessions and more pushed emails it has been 3.5 hours since unplugged and I'm at 80%.... I'm going to have to say that it was the *22899 that helped me.
jv

ahhh battery goodness again
Battery life is worlds better after doing this.
I would go through a fully charged battery in under 6hrs before... as of now ive been on battery since lastnight at 8 and even after a night of usage, no charge overnight, and using it all day today I still have 28% battery.
Thanks a million

You only dialed *22899? didn't do the other steps?
I tried dialing *22899 and it says programming and it reaches to Lock Code password set... and it seems to not be doing anything. Is it done?

Yup. Well I did wipe cache. Don't remember when I did it, though. But at some point after updating to DL09 I did wipe cache. It's been about 2.5 hours since I edited my last post and I've only lost 10% after a few emails and some text. I've even had wireless on since unplugging it. Something fixed it. I did flash a different modem. I flashed http://forum.xda-developers.com/showthread.php?t=908451
jv
edit: forgot to mention that I am using Adrynlyn's test2 1/16 voodoo5 kernel

My results were for dialing just *22899, without doing the other extra steps...
so far 8 hours unplugged from the charger and I'm down to 71% which seems a bit better than previously ...

This worked great. I charged last night to 100% and then this morning wiped stats around 6:30. I have been using it all day with WIFI and 25% brightness and 11 hours later I have 73% battery life left. I also noticed Standby is on 18% which is a lot lower than it has been in the past.
Thanks again for this little tip.
Any idea if just the *22899 will help out a non rooted fascinate without wiping the battery stats? My wife doesn't want me to mess with her phone.

[Q] Broken battery-management?

I have some problems with the battery of my N10. Very ofen the percentage don't go down while using. Then, when i reboot, the battery drops e.g. from 90% to 50%. So it seens the percentage is just not updated...
The other strange issue is that the N10 often shuts down when i disconnect it from the charger. When i turn it on again is says (still) fully charged.
Is there a calibration or something to reset to fix this or is my device broken?

I have the exact same problem. I have even tried installing GSam battery monitor because the stock battery would sometime never leave 100%. GSam will also stay at 100% sometimes until the tablet shuts down from a dead battery. My N10 will also sometimes shut down when I plug in the charger when it does still have power left.

+1 on the above two. I wonder if this is a hardware defect or software issue.

i have the exact same issues!

If you are rooted you could wipe battery stats. Worth a try.
Rom Toolbox Lite has this option under rom management -> wipe options -> wipe battery stats

I forgot since I use TWRP, CWM Recovery should also have this option under advanced.
Also, You should wipe after a full charge.

The Wipe Battery stats feature has been removed from TWRP.
I don't have any of the above mentioned problems but I have noticed other quirks about the battery/charging operation.

It's an hardware issue. Get a replacement device asap.

Performed a factory reset?

Same issue, tablet turns off both when I put on the charger and take off. This is my third nexus and I was so excited because it didn't have light bleed. The first one was terrible and they sent a replacement. That was about half as bad light bleed from two corners instead of four. Google is really slow with refunds and still has a pending charge for the replacement which they received on the 14th of December. My replacement I decided to return for a refund. They received that on the 17th , still nothing from that either. This third one was purchased at Walmart so I can at least get a refund.

Deep Sleep issues?

My phone has not been able to get into deep sleep. For the last few days that I've checked GSam, it's always been at 0s of deep sleep. Just checked right now and after 21 hours, my phone has gotten 10s of deep sleep. I've done a search and looked through many pages of posts on some of the various battery discussion threads but I haven't been able to find anything. Does anyone have a possible remedy for this or explanation of why it's happening? Is anyone else having trouble going into deep sleep?

Mines is the same, I assume it's because I charge my phone every night, which is really the only time my phone would sit still inactive long enough to actually enter doze.

I might of fixed my draining battery issue so maybe you guys can try it out too. My issue was my phone would not go to deep sleep and would stay awake even when the phones display was off so something was keeping it up. I tried all the different methods out there including the package disabler and doing the hard reset with the cache reset. I was browsing the developer options in the settings screen and looked at my running services. I noticed that my contacts and a. Program called com.qualcomm.location had a message next to them saying restarting while all the other programs just had a countdown of how long they were running. So I clicked on each and pressed stop and I also re-downloaded the package disabler and disabled the com.qualcomm.location. after all that I synced my contacts again and just did a simple reboot and after that my phone was able to deep sleep. Now my battery is not draining like it did. So in my case those 2 apps had an issue and kept trying to reset itself so the phone was never able to sleep. I would recommend looking at your running services in the developer options. go into the running services and see if anything is trying to restart itself over and over again

So I did finally achieve deep sleep. I tried a few things from the temporary battery fix thread and I wasn't able to pin point one thing which worked, THEN, I restarted my phone and it wouldn't go into deep sleep again. I tried wiping the cache and restarted and suddenly it's going into deep sleep again....
I'll keep an eye on it and will update if anything interesting happens.

I finally charged my phone prior to going to sleep and it finally did dose last night, the phone has to be stationary to enter deep sleep

Doze and deep sleep seem to be too different things. My phone will sometimes doze without going into deep sleep. What's really weird is that sometimes my phone will randomly stop going into deep sleep and a clearing of the system cache immediately fixes this. There have been at least two times I can confirm I *only* did a cache wipe and the issue was remedied.
Does anyone have any idea why this is happening and why clearing the cache helps?

Anyone figure this out? Also is everyone on stock? Im rooted and on superman rom, this is happening to me every day now after i charge it over night. I have to restart my phone to fix.

same for me on Galaxy s7 flat exynos sm-930f, no root, stock rom
very annoying
if you find a solution suitable for me (without root) please let me know

same here to me stock exynos s7 when plug off the charger in the morning have to restart the phone otherwise battery dies half day

I figured out that for my phone it defenitly is somehow connected to the fast-charging function.
When using the fast-charger the phone doesn't go into deepsleep anymore.
It happens as soon as the phone touches the fast-charger, it doesn't even need to fully charge for this to occur.
When charging with everything else, incl. Qi nothing happens, but as I said, after the fast-charger was connected - no deepsleep.
At least that's what I observed, no guarantee that this affects everybody.

It is the same issue that has been discussed for a while in "high android system battery drain" thread. Read up last few pages.

Battery level stuck

Howdy, everyone!
I have a problem with my G935F: the battery percentage stays stuck while the device is on, it gets updated on reboot but then won't change. If I connect the phone to the charger the icon in the status bar reflects that but the charge level still won't update until the next reboot.
Battery life is great and charging while the phone is off shows the correct percentage throughout, which makes me believe this is not a problem with the battery.
The phone is rooted and I'm on stock 6.0.1. I've already tried multiple full wipes and flashing several versions of the stock rom (including Nougat) but the problem persists. I've also tried clearing the cache and the dalvik cache to no avail.
Do you have any ideas about what the problem might be or what steps I may take to try and fix it? I'd like to rule out all possibilities before dishing out €50 to have the battery replaced!

Maybe you have an app that's interfering with the reported battery level. Does the battery indicator update properly when you boot the phone into safe mode?

Unfortunately, no.

No ideas?
Unfortunately the battery level is still incorrect even when the phone is booted in Safe Mode. However it is correct when the phone is charged while turned off and the battery life is normal, which makes me believe it's not a hardware problem...

Hey guys sorry to bump old thread , but found this thread and its good to not always make new threads Well, i also suffer some heating issues but recently my battery percentage stuck at 82% while i was charging with hotspot active , i dont know why it got stuck , but when i replugged the jack in usb port , it continues but after sometime stucks again at 84% , i cleared cache partition but its still the same. But if i turn off the phone and charge, it will proceed to 100% , so the only changes that i made in system are enabling developer options and installing nova launcher and xwidgets app , phone is not rooted and completely stock. Any hints guys ?

Battery Drain Help

Hey Folks loving my LG V20 so far. But recently, I have seen Android OS, Phone Idle, and Android System draining half the battery life.
I am un rooted, and do not wish to root it as all features I have are there.
Any tips you can provide me? Thanks.

Have you rebooted it firstly?

Have you tried a more in depth battery stats app?
Accubattery, gsam betterbatterystats come to mind
Mine does that in response to installing any new kind of all that scans for media in background. It'll get stuck alot but usually a reboot helps so not sure

Sorry for late reply, I checked my battery health estimate with Accubattery, it shows 94%.
Also, Phone Idle drain is higher then Screen? Anyone else get that?

I have phone idle using as much power as screen use. Sometimes even more.
Not sure what phome idle means. Wifi, 4g idle are included in this?
