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.
Sent from my Fascinate - DJ05/SuperClean/Adryn's 12/30
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.

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.
Hello there everyone!
So, first if of all allow me to say I'm a programmer/network administrator so I know things around *nix systems and Java, and right now I'm having a quite boring problem with my Tattoo.
Here's the history:
Got a Tattoo one year ago, v1.6, all going well, suddenly it started rebooting, some months ago, dropping calls and would sometimes loose network. In the meanwhile I used another phone and left the Tattoo alone.
Now I decided to pick it up again and sort things out.
Problems:
Phone sometimes reboots randomly
Phone reboots specially during phone calls
If I select the use 2G Networks Only, the phone restarts some seconds later
What I have tried:
- Changing SIM card
- Flashed latest version from: http://forum.xda-developers.com/showthread.php?t=939122
- Full wipe as well
- Formatted SD
- Factory Reset
- Cleared Dalvik Cache
Clearing Dalvik Cache allowed me to keep a phone call for more than 30 minutes though.
The weirdest situation is that *every* time I select the Use 2G Only option the phone reboost, some 5 seconds later. Every time.
Any suggestions? Completely lost here.
Shameless bump...
Late, but, I had have same problem when the battery is not calibrated.
I seems to happen when the Tattoo appears to have enough battery, but it not true.
Charging (up to 75%) and calibrating battery works for me.

Charge your battery to 100%, go to your recovery, advanced, wipe battery stats. Then discharge fully and charge 100% again
Great, thanks!!
Yesterday, I switched on the System UI Tuner, specifically the "Show embedded battery percentage" feature. Today, I was on a phone call for about 30 minutes (with screen on) and was not charging at all. Battery level should have been lower than 100% but remained 100%. Rebooted the phone and the battery level is still at 100%.
Anybody else experienced this and/or has a remedy for it?
did you actually check your battery stats? has it moved from 100%? hav you tried turning it off again? there's not enough information here!

The battery stats did not have any information for more than an hour. I turned of the battery percentage feature and the indicator went back to normal.
You sure you didn't turn on Demo mode by accident? System UI tuner allows you to turn on demo mode which will make the battery percent stay on 100%. Try toggling it on and off.

Same issue
hey there.
I have the same issue right now. I just got my 6p yesterday and I have no modification installed at all, although i did unlock.
My battery is showing 100% with no individual battery use breakdowns, and I have rebooted twice and still 100%.
Did you solve your issue at all?
I may do a factory reset and see if that helps.
Have the same issue. It started this afternoon.
I had the same problem . I fixed it by going into recovery (stock), wipe my cache partition, and reboot.
I fixed mine also, went into TWRP wiped Delvik Cache and Cache.

I did the same thing, wiped the cache and a reboot and has seemed okay since. bizarre.
This just happened to me this morning. Was just playing games on my phone for about an hour, then noticed phone still showing 100%. Anyone figure out a sure way to fix this? Tried rebooting.
I understand that bad signal will drain more battery but when I'm at home with perfect signal and wifi I still get pretty bad drain. I disabled wifi and set data to 2G over night and I left with 4% drain after 8 hours. I have no issue with wakelock, no Facebook, don't use snapchat often, super light user. Overall, very disappointed with the A7. I just can not stand the standby time, and I have no idea how to fix it. When I'm in school with bad signal, the battery drain even faster .Come from Iphone 5s which is almost a 3 years old phone(still work like charm, and my moms using it) with literally no battery drain overnight, and it out performance the A7 in battery life by far(with outstanding standby time). Just kindly ask you guys, do you have this kind of issue or is it just me? And any suggestion on fixing this issue?
here is the link for the battery screenshot, I'm a new user so I deleted the http

Did you disable the WiFi scanning? This is commonly a major factor in battery drain in Android phone.
Also, try to wipe the cache and dalvik

In my experience, the WiFi scanning should be disable to help battery drain. Go to location, click the three dot on the top right hand side corner, click scanning, then turn off the WiFi scanning and bluetooth scanning.
You have to boot to recovery to wipe cache and dalvik. Turn off the phone. After it's off, press the volume up and hold it while you press the power button. Once the phone vibrates and ZTE logo is showing, release the power button but hold the volume up. You will be presented with recovery option. Choose wipe cache and dalvik, then reboot. Be very careful with this, don't click the wrong choice. I am not responsible if your phone is bricked because you did something wrong here. If you are not familiar with it, DON'T do it.
For location, I don't disable it, but I put it under "battery saving" mode. When I use navigation, I will change it to high accuracy.
Try the first one and the third ones and see what happens after a few days. If you are still not satisfied, wipe the cache and dalvik (DON'T do this if you are not familiar with it)
My personal experience with this phone, I can have 5 to 7 hours SOT depending on what I do.

The main issue is the RF signal and standby time drain huge percent of battery. Disabling wifi scanning will reduce the drain but only on wifi portion. there is the link of my screenshot I took after disabling wifi scanning and location. Did not fix battery drain on idle issue.

If I look at the attachment, you use the phone for 13.5 hours since you charged it and you still have 78% of battery left. If that's the case, I don't see a problem with that.
The 41% of RF signal usage is out of your hardware battery usage (75%). So, in reality, it's 30% of usage which represents 6.6% of overall usage (30% x (100-78)%). It seems to me that you had the phone connected to wireless data during this time, not your WiFi? If so, that's normal.
I get 3% battery drain overnight at most.
Don't see any problem with that.
That SoT is with streaming movies etc. YouTube a little gameplay and Facebook.

That's pretty good. I'm not getting that. I average 5 hours. Will see what the latest 7.1.1 gives me.
I mostly just surf the net and check emails so I should be getting more.
Hi, guys have any of you been able to solve this issue? I'm currently using stock 8.0 and I have just replaced my battery for a new one and still RF signal and Standy are killing my battery (even using airplane mode).
I don't know what to do. I have tried going back to android 7.1.1. and 6.0 with no luck. I have tried several factory resets, I have wiped cache, I just don't know what else to do. My phone's battery is simply dying for no apparent reason.
I will post some Gsam screenshots before my battery dies.
I will post the screenshots later on today. But I can say now there is a major problem with the standby of the phone. So I fully charged the device this morning and battery has dropped by 15% in 4 hours simply from standby (I haven't used the phone).
---------- Post added at 01:15 PM ---------- Previous post was at 12:52 PM ----------
My problems keep getting worse. Now I'm stuck in FTM mode and I can't get out. I have tried every single combination of buttons for way over 10 seconds with no luck.I guess I will have to wait until the baterry dies and hope for the best.
Something went finally the right way! After several attemps I have been able to reboot the phone via the "adb reboot" command while stuck in FTM mode.
Back to figuring out what to do to improve the phone's battery. While stuck in FTM mode the battery went from 80% to 60% (screen was on obviously in FTM mode) - 4 hours aprox.

Had the phone shut down on me twice now, while using the camera and gps on (no cell network), after just a few hours of use from full load. First time, when I went to recharge it, the battery was at 24%; the second time, it was at 68%! WTF?

Looks a little erratic to me.
Did the phone shut down while using the Camera and GPS on both times? Do you have other apps running in the background?
It seems like an overheating problem.

cmmx said:
Yes, camera and gps both times; I was testing several cam apps, the second time. But it was because of the battery, not temp. - or so it said.
Update:
Tried again today, and, switching off all radios (Wifi, which "Smarter" Wifi Manager didn't disable, even though I was kms away from any known network, GPS, NFC, BT and Cell), it took the phone the whole of 9 (nine) minutes to go from 99% full to the ultra mode and switch off (which happened at the same time, btw) with 24% of power remaining.
Was testing different camera apps, cycling through them and flushing memory in between (unlike last time, where they all were loaded the whole time), and all I was able to take was 22 pics, and the battery was dead.
Then, 15 minutes after a last attempt to power it back on, connected it to usb, and the battery was at 74% - you go figure.

Bummer...have you tried uninstalling every Camera app you have and use your phone for one day just using the preinstalled one?
In 22 camera apps, perhaps some of them are bad and may cause your phone to randomly shutdown (i have no explanation for the battery percentage randomly showing tough)
Can you provide a list of those camera apps before uninstalling them?
EDIT:
Does the phone shutdown if you're using those apps while charger is plugged in?
...
cmmx said:
It doesn't happen under regular use, so I don't think that's the cause - and it wasn't a system crash, anyway, the ultra mode warning showed up, and the low battery/shut down just popped up on top of it.
The apps I tried:
Open Camera 1.40
Bacon 1.10.2
FV-5 3.31.4
Snap 8.2.7
Proshot 5.0.8
Footej 2.11.113
Nope, the phone never shut down on me while plugged in - individual apps, yes, but the phone itself, no.

Have you tried wiping the cache?
To wipe the cache partition, follow these steps:
Shutdown phone
Hold the Power key and Volume Up for about 8 seconds.
Use the volume button to select Wipe Cache Partition
Press Power Key
Restart phone after "cache clean complete" by selecting "reboot now"

Update:
So, either the battery is dying, or something is wrong with the phone: just went to my veranda to take some pics and, in less than 2 minutes, it went from 100% to shutting down (again, shuts down as soon as ultra mode pops up); plugged it to usb, and it showed 83% battery; pulled the usb cable and it status icon was at 80%. Went to try it again, managed to take 2 more pics and it shut down again; went back to the pc and the status icon was empty; plugged to usb, and it was at 73%...

Sorry for the late reply.
Plugin your phone to the computer, open a Command window, navigate to the folder you have adb extracted and type:
adb reboot recovery.
See if you can clear the cache partition.
If you have questions about which option you should choose ask first before selecting!
