Alot of people seem to be saying their phones drain the battery too fast. I wouldn't know because I don't have anything to compare against. Figured I would post it here so others could compare...
Method: Left phone on charger overnight, took off charger and immediately rebooted phone. (Status showed 98% after reboot) Did not reboot or charge phone at all during the day.
Eight and a half hours later...

I consider this plenty of battery life. I had numerous chances to put my phone on the charger and didn't do it because I was testing it.
Ill check mine tomorrow and get back with you after a full charge tonight. I have a charger at work i plug my phone into whenever i am not listening to Music because i have to use the USB => 3.55 jack.

that seems like a really low voltage... aren't the G1 batteries rated at 3.7v?
EDIT: sorry i didn't notice the battery level was at 9 and 25... that seems about right, I was looking at the battery scale and got really confused.
mine goes almost up to 4200mV (~4198 if i remember correctly) when fully charged on the charger. It drops to somewhere between 4000-4100 when I disconnect though.
I am running the 1400mAh seido battery, but pretty sure the stock HTC one did the same.
For a lower bound, I think about 3.5V (3500mV) is where the 0% cutoff is for me.
One key thing to battery life many people overlook is signal strength. I worked in a building earlier this year with really bad signal (0-1 bar) and my battery would drain like CRAZY because my phone would search for signal the whole day. I verified this using the Watts app and battery drain during the mornings and evenings was significantly less than the hours I was at work. I started to keep my phone on airplane mode at work since I barely got signal anyway and it helped tremendously.
here's my battery info anyway after about 12 hours of 2g, no data (t-mobile killed the web2go apn ) a few texts and phone calls.

does the "battery level" means the % of the remaining power in the batt?

if so........y does the battery level went up after a reboot in the first post?
Anybody having problems with longer than usual charging times, as in it takes forever to charge, today I connected it to the charger at 80%, an hour later it was only at 86%

yes that happens to me as of lately but what i do is i reboot the phone and to my surprise is charged all the way after reboot.
lately i've been saving alot of battery power using "toggle data" app to turn off 3g/edge whenever im not using the phone, just flick it on when i need to and flick it off before i put it in my pocket, I work at an airport so while I may have plenty of outlet's to utilize I don't necessarily want to leave my phone unattended where shady ****er's can thief my ****.
cant give precise levels, but usually recharge to 100% overnight and by 6pm i'm somewhere between 30-50% depending on how much i've been able to us the phone inbetween actual work, and that's from about 7am, while that's not too bad G1 wise it still sucks cell phone wise heh.
also I found turning off the data while chargin definitely helps.
the G1 "phones home" every 5-7min when data is on which is why the data can drain on ur batrery and digg into ur pocket if your abroad w/ roaming on

=========================
No phone calls, about 100 text messages, about 10 minutes to 20 minutes of web browsing, looked up two locations using google maps, and sent/received about 20 or 30 emails over exchange with push. Not too bad, but not as good as it's been in the past. Most notable battery drain was during web use.
I am Runing Cyanogen 3.6.5 right now

Alomost 8 hours later after some medium internet web browsing and edge that had to search and search for weather updates (i was in a building with a metal roof) However i did only one text and one phone call all day and that call was to my voicemail. This is not so bad but not so good if you ask me.

Seems like there are way too many variables to reach any reasonable conclusion IMO.
hey.. how are you guys getting this information from? Is this a application? or where do I find this information so I can post and possibly help out. Thanx a lot guys
i will say that the best way i have found to get the "most" out of a full charge is to do the following...
Let phone charge up to 100%, for instance, overnight or whatever...
Then, power off phone...when you power it off, make sure that the red LED turns green indicating a full charge...sometimes even after a 100% charge, when you power it off it still needs to charge a little more
Now, power it on and you will have effectively "synced" your battery level with what android reads. This is by far the best way i have found to get the most out of a charge
I have a problem and not just any ... now he writes about what's going on.
I absorb all of the batteries within 12 hours no matter what happens I read lots ofposts on the web but I was a strange coincidence after charging the battery to get the complete 100% to 0% discharge is 12 max 13 hours on stanby . SpoonChargeprogram shows the temperature of 31 degrees Celsius and does not drop even though I put in, the place where the temperature was 16 degrees this has notdecreased (tried on two original batteries in which one is new), the CPU clock speed is low is exceeded 50% did not fall off so that it cuts processor. I have uploaded for fun original ROM, ROM, 826X, and now Venus 2.4 without changes ...I did Task29 >> ROM >> HARD RESET >> reset and still nothing. Yesterday I charge the batteries into the full and off Xperia today are no longer included the empty battery ... hands fall off. Is the fault of the electronics in the middle? and what you can do about it. Has anyone had similar? Please help
Sorry for my english is not very good
I left my phone to charging the battery and after two hours I just checked it and I saw that it was literally burning....
The battery widget showed me that the phone temperature was 60 Celcius degrees and the battery didn't charged.
I have encounterd overheating while playing hd games but never while charging....
What it could be?
Sorry for my bad english!
Hi i bought a galaxy tab s 2 about 2 weeks ago it's really good device but yeaterday when the battrey goes 1 % the horizantal lines appear on the screen and after 5 secends mt tablet shtdown is it normal on s series to shutdown like this in low battery or it's my tablet problem??
can confirm mine has done this once...will post if I have further issues
Same on both my 810 and wife's 710. Usually happens as it goes below 10%. Lucky you get down to 1%. Received with 5.0.2 + 2 additional updated have not corrected the issue. If it did a normal shutdown that might be ok, it's the way it dies that concerns me.
Same happened to me once when battery was at 2%.
Same here on T715 .. don't like it and freaked out when it first happened .. glad to know it's not only me but still don't like that it dies like that!!
guess the % battery display isnt as accurate as we think,so if it shuts down at a higher % than 0% its because the battery really is below the dangerous values.
If LiPo batteries fall below a certain voltage,there is no coming back .. means the battery is DEAD.
so be glad that the safety shutdown works so well,and dont let your batteries run that low often !!!!!!!
ideal is a charging state of 40-80%,so better to charge it short more often ,instead of a 0% => 100% charge all the time.
This will increase your battery life !!!

Agreed. That's what the low battery warning is for.
Mine does it consistantly at 15%. Ridiculous.
I got a 810 and I got the same problem!
I hope it's just a badly calibrated battery and not a bad batteryconnector! http://forums.androidcentral.com/sa...lickering-power-problems-like-tab-12-2-a.html
