I have a stock Motorola defy+ updated to 2.3.6. Been using it less than 6 months.
I have about 150 apps. About 50 are games and all games are transfer into my 64MB of sd card. The rest of the apps are in the phone memory.
Recently the phone started constantly automatically rebooting usually after i change battery, it will stays on for about 2-5min after the reboot, then it turn off and reboots again. This goes on for about 3 cycle before it all went well. At times it only auto reboot once after start up.
Initially i thought its the app so i reset the phone but still this occurs.
Everything seem normal and functioning well except for the few ocassion everytime when i change to a fully charged battery (because i have alot of spare batteries) , it will reboot again and again 2-5mins after the reboot.
This happen everytime i change to a full charged battery, does the battery got to do with it?
in addition, my phone is always very laggy too and whenever I run too much application that consume alot of memory, it will reboot itself too but that happen seldom. My cpu consumption is also always very high and i wonder why because do not run any major background processes except those from Motorola service(quite abit), Super task killer and NQ mobile security app.
anybody can offer advise?
Thanks.

If ur phone is rooted try overclocking the CPU to make up for the number of apps. Also try partitioning the SD card and putting the apps there instead because if u put so many on the SD with apps2sd the phone gets real slow as it loads all of them
Read about rooting, overclocking and partitioning

Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.
Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.
Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.
My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.
having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.
You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

Restart your phone in safe mode, and see the battery drainage...maybe it can help you.
It seems good for me

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5
I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.
Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....
I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.
Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.
Update
Please refer to the OP for update. Thanks all.
battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?
It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

Hello,
I bought a Lenovo S860 phone some time ago and I have several questions on how to get rid of some annoyances.
The phone has 2GB RAM, and Build Number = S860_ROW_S402_141108, Android v4.4.2
(I know there are some official updates, but I rooted the phone after I bought it, and I don't have enough free time nor patience to invest in a backup + unroot + update install + re-root + restore backup).
So here are my questions:
1. Every time I connect to WiFi or Data Connection, in the Apps section of the settings, under "Running" and "Cached Processes" there are always some which I don't use/want to be active. For example, google play services, hangouts etc. I always have to manually stop them but sometimes they get activated again even when there's no internet connection. So, is there any way to force the OS to disable caching of certain apps?
2. Sometimes the data connection on my first SIM card does not activate. I need to activate it for the second SIM, then for the first again. Known issue? Solvable?
3. Sometimes the signal for both of my SIM cards appears cut off (there's a small red X on both of the top right icons). Only way to fix it is to restart my phone (which takes forever), and the biggest problem is that it happens out of the blue (nothing else changes too, I keep the phone in the same place and suddenly I can't call anyone nor receive anything). Any ideas on what might be the problem?
4. After recharging the phone to 100% (and doing the calibration at the same time), the battery seems to drain a lot faster until I restart the phone. Another related issue (to recharging) is that the battery percent(%) is not always accurate. It happened many times that from 60-70% it got to 15% suddenly and started to give me warnings. Is there any way to make this batter sensor work properly?
5. How to speed up the time in which the GPS finds my current location? If I'm standing in one spot it takes even 5-6 minutes sometimes. After I start driving the car, it usually converges after 2-3 minutes. Other phones with the same Android do it in under 30 seconds (so I guess the OS is not really to blame).
6. How can I take a screenshot with this phone? I've tried like 5-6 apps and key combinations (like Power+VolumeDown) but nothing is working.
7. Is there any way to have the "flashlight" led open even when I lock the phone(i.e. Power button)? Again I've tried some flashlight apps but I have to keep the phone unlocked all the time or the led shuts off. I'm using a drawing pattern unlock with my phone.
8. There were some threads on these forums (but I can't find them anymore!) about Android 5.0 on Lenovo S860. Did it come out yet? or, at least, are there any stable 3rd-party versions of it?
9. Is there any custom OS that works well with Lenovo S860? (I'm thinking Cyanogen)
Thank you
Can anyone help with any of these questions?
After my original phone went into bootloops after the marshmallow update, I got a replacement within 1 day (thanks, AT&T, they really surprised me with customer service on this one). Unfortunately, my replacement has been full of issues. For starters, I used to get maybe 1% per hour max battery drain with idle and screen off with location and sync on (would be 97-99% in the morning if it was 100% before sleep), but now it is 5+% per hour, same battery as before, even switching it with my spare, no difference. I have Greenify installed and have a decent number of things greenified, but I don't want to have to also turn off location and sync just to get still worse battery life than I had before. A factory reset did not fix the issue. Google Play Services seems to inexplicably be taking more battery than phone idle now but it is not enough to be explaining this battery issue fully.
Also, I get lag in various applications, including pre-installed system applications. Most noticeably, Chrome and Chrome Beta have the same issue of freezing 3-10 seconds before the page is completely loaded which is an extreme nuisance. Reinstalling the apps and clearing the cache/data did not help. Various system applications run with lag too. I moved some applications to the SD card and the settings app was lagging so terribly it crashed a few times.
Any ideas to my phone woes?
Hi
I've got a brand new PH-1 and haven't yet had time to set it up properly, only started it up, let it update software and used for an hour or so before testing the idle battery drain.
I haven't installed any apps or changed any settings other than to disable the google app (to prevent it listening for or responding to "ok google"). I tried out the 360 camera, signed in to gmail and browsed a few websites, before charging back to full and restarting the phone before this test anyway.
But leaving it idle with the screen off and with phone network disabled (there's not even a SIM inserted), only wifi on with good signal, it lost 65% battery in under 22 hours. Screen on time was less than five minutes.
Is this a hardware issue I should RMA, or is it considered normal? If this is normal and there's no easy fix, I'll probably end up having to return the phone anyway for a refund, because if it can't even last a day and half in idle there's no way it would last a reasonable amount of time with normal usage.
Any ideas?
Thanks
Since there isn't a sim card installed, try going to airplane mode and then turning WIFI on.
I am getting about 1.2% drain with cell network and wifi enabled along with all my standard apps installed.
On a typical day with 1-2h SOT, I usually have 60-70% battery left at midnight. I'd try to reset the phone, and then testing again - occasionally a system update will end up doing something funny
I left it overnight with airplane mode on, so even wifi was off, and it's a little better but not by much. Screen on time was one minute.
With airplane mode on, screen off, no dodgy apps, the phone really shouldn't be doing anything to drain battery.
I'll try a full factory reset and see what happens.
Just to follow up, a full factory reset seems to have fixed the issue. Even after doing the same things I had done before (connected to wifi, updated, logged in to gmail, etc) the battery now drains at a much more sensible rate.
Very strange that a factory reset made a difference since it was new from the factory when I had the issue, but I guess something strange happened in the update like dsip suggested.
Thanks for the help!

That's ? percent normal behavior. Anytime you flash a ROM (new phone =new ROM) you need to wait a bare minimum of a charge cycle (more like three in my experience) before you get the slightest idea what your actual battery drain is going to look like. think of it like breaking in the engine on a new car.
