Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.
Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.
Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.
Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?

Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.

I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.

Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!
27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.
I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.
I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!
Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!
I need help, Since the last month, my Xperia z1 keeps turning off at 60-50 % battery. When i turn it back on without a charger plugged in it's at 1%, but when i et it charge for 2 minutes, its back at around 60 percent. Sometimes it won't charge, charge very slowly or even drop 20%.
see image for an example.

I've had the phone for almost 2 years now.

Thanks alot in advance!
Sorry for my bad english, it's not my primairy language.
can't post any links yet, made an account just for this problem.
Your battery is dying... You need to go to a service for a battery change because this one is at the end of its life [emoji52]
I had the same problem. I changed my battery and the problem is GONE.
Since Z1 has a non-removable battery, how much do you guys pay for the battery repair ? does it co$t a lot?
Hello
I had the same problem I have to try everything. Finally I have to change battery and everything works again as before. I have had this problem since the transition. kitkat of a lollipop
what the heck do you mean by you charge the battery and the problem is gone? The problem is the phone can't survive long without charging - you can't just charge it all day long. I know because my battery has become so bad that my phone can die at 95% (and same as op, become 1% and then jump up to 100% quickly). It used to do that only when I do intensive tasks like Chrome and camera, but now it just do that for no reason. Thought it was a software thing so I was excited to get back onto XDA after several years - but got very disappointed afterwards. Here in Sweden swapping a battery costs something like $88, which isn't quite worth it considering I'm prolonging a two-year-old phone's lifespan, so I'm giving up and probably heading for the Oneplus 2 instead. So long Sony...
I bought my X98 Plus especially because of the promised battery life, but I am utterly disappointed. The standard scenario is the following:
- immediately after charging, the battery is draining approx. 0.7% per hour, meaning that I loose 5-7% overnight
- after even the slightest use of the tablet (browsing web, facebook, etc) standby battery drain increases to approx 5% per hour.
in reality it means that I am charging the tablet overnight, disconnecting it in the morning, browsing the news for 20 mins, putting it away (with 90+% battery remaining), and in the evening the battery is around 50-60% with the tablet being on the table untouched the whole time. if I forget to check the tablet in the evening, the next time I am touching it it has a dead battery already.
the same behaviour is present both in Widows 10, stock Android, Mirek's custom ROM and RemixOS. I have the feeling that with the original BIOS the situation was slightly better, but I have almost immediately upgraded to 3.00 (and then 3.02) so it maybe just a placebo.
Do you have any idea how could I troubleshoot the issue? I am aware that the problem is that the tablet is not entering standby/deep sleep mode, but I have no idea how to fix it, since the issue is present with fresh install of different OSs
Hello. I need some help with my new (like 3 weeks old) P20 Pro (single sim, no root).
I'm really happy with this phone now except for one thing. That thing is Standby drain.
I lose like 1-2% PER HOUR over night, doing nothing.
I left my phone last night on 25% and went to sleep.
Next morning, 7 hours later I was on 13%, losing almost 2% per hour.
In my opinion, that's just too much for doing nothing on the phone.
I'm not an expert reading those battery stats, but I dont actually see a problem.
There are no wake locks and the only apps that use the battery are Android-System, Kernel (Android OS) and Google Play-Services.
Huawei Health and Google Play-Services used the Sensor time a lot, but I don't know if the sensor time is important for the battery.
If you have a solution, please give me an advice.
My dad gets the same phone next week and I wanna get it done untill he gets the phone, so I can do the same.
Things I've done:
- wiped cache
- reverted to factory settings via standard recovery
- debloated (like 15-20 apps)

Big thanks.
Trust me, you're experiencing the same thing I have been for the last 6 months. It takes around 3 weeks or so for the phone to learn how you use the battery and from what people have told me on XDA, Reddit and Telegram, this battery drain is "normal" which I still don't believe. I had a Redmi Note 5 Pro before this phone and it probably drained only 2% overnight over 7 hours and I could hit SOT of near 11 hours on a single charge so idk what Huawei has done with the battery optimization of this phone as my Note 5 Pro also had a 4000mAh battery like this phone.
All you can do is continue using the phone and hope it stops soon or maybe think about replacing it with a better phone
Hello i have, from now 3 weeks, a battery problem, well two. I don't know if that's related but since i connected to the uni wifi this problem started to occur (after i restarted the phone.)
So i loose an average of 2% per hour on standby and even when the phone is off.
Just for a comparaison there's a screen from the 19th of september and one from today, the battery go down even when not in use but also the battery usage of apps seems high, and is incorrect as i can see that it doesn't use that much battery.
Does someone have an idea of what can I do ?
I already cleared the cache once, did all the updates
