I've been using my HTC Diamond for a few days and I would like to ask a question.
How are your batteri time? Mine seems insanely low, for example tonight when I put the phone besides my bed with almost fully charged battery and woke up 9 hours later and it was completely empty.
Are this normal or have I probably installed some strange app that drains a lot of battery? Or might the battery even be damaged?
The only app I can think of is the background changer that I found on this page, but it only changes once in 30 minutes, and not when the phone is in sleepmode (I think).
Thanks in advance.
Hi,

Thanks for the tip, gonna check it out right away!
I don't know if I am the only one seeing this, but when I had Eclair, I had crap battery life, to the tune of 10 hours or so. (Granted this may not be crap for Nexus One but it is crap based off past phones I have had.) I installed FRF85B last night and discovered some weird glitches.
First off, when it was in my car dock, it wasn't charging yet the battery life kept dropping, I powered off the device, and powered it back on 10 minutes later (still in the dock) and no change stayed at 91%, still wouldn't charge. I then powered it off, took it out of the dock, plugged in the car charger cable directly and powered on my N1, when it turned on, it said I had 100% battery life. I then plugged it back into the car dock, and voila it started charging.
Secondly, originally when I had unplugged my N1 this morning I used it for about an hour at 5AM and it dropped 2% I plugged it back in to top it off expecting the same crap battery life from Eclair, yet so far, my phone has been fully topped off (from the car dock) for the past 40 minutes and I've made about 20 minutes of phone calls on it, yet it still is reporting 100%. So either Froyo can't properly report battery life, or it has the potential to have absurd battery life. Anyone else experiencing anything like this?
First off - you still didn't search this forum, so you're still thinking that an overcharging protection that doesn't allow you to charge unless you drop below 91%, is a quirk. It's not.
Second, wiping battery stats and making battery calibration procedure ONCE will give you a good starting point to measure something.

The quirk isn't that it wouldn't let me charge that way, the issue was, my battery reported 91% yet when I rebooted the device with the charger directly plugged into it, it immediately showed 100%. So pretty much over the course of 30 seconds I gained 9% battery life.
I wiped my device to factory settings before upgrading to Froyo, and after as well, since my device is not rooted, my understanding is I cannot wipe my battery calibration log.
I did drain my battery fully after upgrading to froyo last night and did a full charge as well.
What you're describing looks like the statistics of the battery is "lying" a bit. I believe it can be thrown a bit off by trying to charge it when it's in 91-100% range, but I don't know the exact way it works, so I can't say much about it.
Indeed, if you're not rooted, wiping battery stats is not an option. Several times of full charge and long discharge (you don't need to go below 20%, to prevent harming the battery) are helpful in correcting the statistics.
If you get a chance to try, please repeat this again (having the phone at >90%, turning it off, plugging it into the charger and turning it back on). If it shows "Charged" again - it might be a bug worth reporting.

I'll have to try it again tomorrow morning, first see if it happens under the same circumstances and go from there. One thing I do remember is the widget I was using "Battery Left" reported that at 91% I had 4100 mAh left in it, which was interesting, and when it went back to 100% it had 4120 mAh which makes me think the OS wasn't actually reading the voltage and thought it was just draining the battery instead.
EDIT: Just realised I had my wall charger with me, battery was at 90% figured I would try, real quick to attempt to replicate the problem, I was unable to, with a direct battery connection, but it could be due to a voltage issue or be related to why plugging it in directly to the car charger resolved the issue. My gut feeling is, it has to do with the dock itself and the pins it uses.
my battery often is charging and it hits 93% and immediately jumps right to 100%. it skips the last 7% or so. i think what is happening is you just finally experienced this issue, which many of us have already posted about in battery threads, but it just happens to coincide with froyo so you are thinking its new and related. the nexus ever once in a while battery meter just gets thrown off and will jump up to 100% because it really was full, just had to catch up the meter. you really should pay attention to the voltage more than percentage, using battery life widget. i know my battery is fully charged at 4.172 volts. and sometimes it hits that but still only shows 94%, so it adjusts itself in one fell swoop.
The issue is I did an extra full charge about an hour ago so I can make it till midnight and it went through all the numbers from 89-100 with no issue

Addendum: Also it seems to be voltage is not that good of a decider of how much my charge is. Before Froyo, until I dropped below 94% I was always above 4 Volts, now I drop below 4 Volts at 96%.
So this morning I was able to replicate the problem, only it was outside of the car dock, I was able to get this problem to reoccur with the wall charger. I unplugged it from power, used it a little bit and then topped it off for the day, it was at 96%. I saw the green light go on, and thought nothing of it, 20 minutes later I went back to it and it was still at 96% and showed that the battery was fully charged.
I checked the Battery Left widget and it was saying the battery was fully charged even though it said 96% left also. I did make a crappy video uploaded to youtube from my backflip to show as well what I am talking about.
AFAIK, The green LED will light when you're anywhere above 90%. It's not a function of charge being complete. Check it.
Also, if you plugged it in with 96% - this is the behavior to be expected, since the phone won't start charging unless it has below 90% to begin with, and it'll show "Charged" - because it's not charging (to prevent overcharge).
Again, fail to see any problem in what you're describing.

Yet my phone has always been able to charge when above 90% before froyo. This behavior is new to froyo for me at least.

It means that you've never paid attention to that until now. It's working this way since the phone was out (with stock Eclair) and if I'm not mistaken - it's not controlled by OS at all.
I did pay attention to such actually because of the fact that I had been getting piss poor battery life. This has never happened before. In the morning I would use the device a little then top it off because I noticed that works give better battery life.

Well, you had a buggy phone that has now corrected itself. Welcome to the way it was supposed to work from the beginning.
Topping off the battery at 90%+ contributes to battery degradation - heating from overcharging. So you were actually damaging your battery.
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.
Same Here
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.

JROCK
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!
First some history. Running Jaybob 2.3.4 June 4th. With the .35 kernal. But had the same problem running Aosp 2.3.4 also with the .29 kernal. Firerats 1.5.8 I think it is. Mtd 95 20.
Now the problem, Sometimes I will charge the phone over night and in the morning it will be at the same battery percentage as when I plugged it in and sometimes it will show 100% but then unplug it and it drops to the exact level as when I plugged it in instantly. Other nights it will charge full and stay there. Have had same results with different cables and chargers. So last night after installing June 4 Jaybobs I let it charge all night and this morning it read 100% so I went into recovery and wiped battery stats and rebooted. After reboot it read 74% the same as when I plugged it in the night before. So I let it charge for an hour and a half and when I checked it it was at 74%. I unplugged and rebooted and plugged in and now after an hour it is at 91%. That is where i am at. I plan to charge to 100 and wipe again. Any insights into this problem? Anyone seen this before?
Edit. After charging and wiping battery stats it is at 100 after unplugging. Will let die and recharge and see what happens.
I seem to have a similar problem. I usually turn off my phone every night and let it charge. First thing in the morning, it always reads around 82% instead of close to 100% like it should. This has been happening for the past couple of months now, on completely different Roms too. Like you, I also wiped my battery stats at 100% and it didn't help. Whats also weird, is last night, I left my phone on and it charged up to 100%, but the first ten minutes after I took it off the charger, it was down to 82% and 30 minutes later (after actually using it) it is at 80%. So pretty much it fell off of a cliff and landed at 82% and is now acting normal. I know this doesn't answer your question, but it assures you that you're not alone, and I'm searching for a solution too ;-)

i had the same issue a few months back. i fixed it by charging it from a computer usb port (it will charge slower, but from what i've read thats actually better for the battery). I let it get to 100% and left it connected for a while longer, then wiped my battery stats. from that point on it seemed to report the proper battery level.
I noticed that the ac charge adapter would charge it to 100% way too fast, from 12% to 100% in like 10 minutes if the phone was powered off. i knew that wasnt possible, so thats when i did the usb charge / battery stats wipe, and it seemed to fix it for me.
Problem was getting worse, did ruu and re rooted and seems to be fine. Will report tomorrow after more testing.

Hi guys, I've a problem with my one.
Sometimes the battery percentage get stuck on a value for a long time, even if I keep stuff running (that usually drains battery). Tonight happened again in such a strange way..
The phone turned off yesterday evening at 0%, so I plugged in, turned on the phone, used another bit and than setted in plane mode so I went to sleep. I woke up in the middle of the night and noticed the green light so i took the opportunity to pull the plug (to avoid overcharge). This morning i notice battery percentage at 77% and battery stats with no app activity with cronology time on 32mins (I pulled the plug 4/5 hours before). Now I'm using the phone from more then an hour and it's still at 77%.
Is this an hardware or a software problem? I have stock rom update to lollipop version.
Do you know how can I try to solve this?
Also if i leave the phone unplugged at night it battery drops down 4/5% and in the battery stat i can see "standby 100%" with 100% of the time "without signal".. in the battery cronology wifi bar looks always active
