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.

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

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

Is there a software that control how your battery will be charged?
I know there is a tweak that allow your device to connect to your phone and sync without charging it.
However, I'm looking for a program that will let my battery drain till like 2% before it start charging. The reason I want this to happen is because it'll improve the performance of my battery. It's always good to drain out the battery before fully charge it again.
I don't know about any app that will do that for you, but no charging while syncing can be done in the settings:
settings/system/energy -> Don't charge while conected to PC
Interresting?
You said you want to discharge your battery to almost 2%
Mayby interesting to read the story about Li-ion batteries.
http://www.batteryuniversity.com/index.htm
They say that's it isn't always good to discharge the Li-Ion battery totally.
besides:
Low Maintenance - no periodic discharge is needed; there is no memory.
Good Luck,

this is totally wrong
you drain the ni/cd batteries for better performance not the cellularphones.
you drain the cellularphones battery ,potentially kill some battery cells.
drain it to 2% more than 15 times kills half of it capacity and/or age.
I am going to try and not leave anything out here....
This first started while running Cyan 3.6.8.1 with 1.3 recovery, 26I radio and HardSPL. I was running the overclock widget and I stupidly set the high and low to 528. What this has to do with it, I dont know. Ever since my battery has been very bad and very wierd.
It will drain very quickly. (I have owned my G1 since November so I am aware how short the battery normally lasts) Re Flashed, wiped, tried 1.4 recovery, tried JF's ROMS, older stable Cyan's ROM (3.4.something). During this time I could not hit 100% battery, even after a 15 hour charge. At this point I bought a new stock battery and a 2300mah battery. Even though the 2300 seemed to last a little longer, it still dies within hours.
I got it up to 99% and deleted the batterystats.bin file through the terminal and still nothing. Also, I let the battery run down until the phone shut off a couple times durring this whole ordeal.
It seemed like I had no other choice, but to unroot. I then got the OTA to CRC1. At this point The battery wasn't dropping as quickly and I actually hit 100%!!!!!! Things seemed to be going my way. Over the next day it was great. Then once again it turned for the worst. I once again couldn't hit 100% and now it seems to stop charging at random points... once at 98% then 71% then 63% then in the 70's again.... You get the point. I am using the BatteryLife widget and while watching the extended info totally freaks me out. While I was not charging I watched to mV go from 3808 and 58% battery to 3816 and 52% battery! How can the mV's go up with the phone unplugged?!?! How can the % go down with the mV's going up?!?!?!
Any ideas????? Anything would be greatly appreciated.
Thanks
I think mV is the drain on the battery or the actual volts in the battery. For example, 4000mV may be 4.0V, however in Cyan v3.97 there's a feature in Spare Parts under Battery Info that tells you your battery health.
For example, mine is currently:
State: Charging (AC)
Bat. Level: 54
Battery Scale: 100 <-- Dunno what this is.
Battery Health: Good
Battery Voltage: 4128mV
Battery Temp: 33.3*C
Batt. Tech: Li-Ion
If you get "Battery Health: Bad" well, replace it. Also, with the battery not charging 100%, it could be getting too hot. Maybe pop it in front of a fan or something?
the battery scale is just the scale it uses to determine the battery level. scale of 0 to 100 battery level of 0% to 100%. i do not know why your battery level is depleting at that rate. clocking it to 528/528 will drain battery faster, and when it freezes at a percent try rebooting the phone and see if that corrects what the stats are displaying for the charging percent. it has been documented in other threads that the battery will freeze at a percent but fix its readings upon a reboot
I dont even need to reboot it to "unfreeze" the percent. Just unplug it for 5 minutes and plug it back in. I know clocking to 528/528 will drain it faster, but that was long ago as I am now unrooted trying to fix this. Also, when I say fast, I mean fast. Sometimes it will go from 99% to 50% in about 20 minutes with the phone at idle.
Here is the way my WiFi N7 (rooted-) stock 4.2.2 battery behaves. I believe this to be a battery exhibiting nominal behavior. Perhaps this info will be useful to others for comparative purposes, when they ask the question, "what is normal when it comes to charging?".
- On the 2A OEM wall charger & OEM cable, charges from ~10% to 100% in ~ 2 hrs, 30 minutes.
- The exact same result (2 hrs 30 min) occurs independent of whether my N7 is completely off, or powered up but sleeping (screen off)*.
- Battery voltage at completion (100%) charge:
---- with AC adapter still plugged in: 4.193v
---- 30 sec after unplugging AC adapter: ~4.14v
- Misc battery curve points (during discharge):
97% 4.099v
93% 4.075v
89% 4.031v
80% 3.935v ( note approx 1% per 10 mV here )
78% 3.955v ( note hysteresis - this observed after 10 min of "sleep")
68% 3.867v
52% 3.764v
48% 3.757v
44% 3.735v
39% 3.711v ( note approx 1% per 5 mV here )
36% 3.707v
28% 3.684v
16% 3.638v
8% 3.538v
6% 3.528v
Other Notes:
- At the date of writing this, the tablet has been in service for 3 months of daily use; it was manufactured in Dec 2012.
- I do nothing special to the device in terms of a charging discipline; when I get done using the tablet, I put it on the charger. It sits there (on the 2A charger) 100% of the time when it is not in use. This means that it normally is idle at 100%, and gets recharged to full capacity from random discharge conditions - only rarely from a deep discharge condition.
- This thread is about charging and battery voltage range - NOT about discharging results under random operating conditions. *Having said that, it is important to point out that comparing charging rates between devices that are sleeping can be like comparing apples to oranges: the possibility of variable charging current available to the battery due to user-caused configuration differences (or cell signal power usage for 3G N7s) is quite high. IF YOU WANT TO FIND OUT IF YOU HAVE A BATTERY OR CHARGER ISSUE, TIME THE BATTERY CHARGING RATE WITH THE DEVICE TURNED COMPLETELY OFF - NOT BY "USING AN APP". Also, you should inspect the battery voltage range as well rather than relying on a "% charge" value; the former is an actual measured value and the latter is a computed (synthetic and thus possibly unreliable) value.
- battery charge % and voltages reported here are taken from values in the
/sys/devices/platform/tegra-i2c.4/i2c-4/4-0055/power_supply/battery/
folder
- If you watch the battery voltage behavior carefully during discharge, you will note that it does not drop monotonically; for instance, if you sleep the screen for a minutes or two and then check the battery voltage immediately after turning the screen back on you will find that the voltage has risen slightly - even though the "% charge" value may have gone down! Both of those observations are perfectly normal - the Li battery cell voltage will "rebound" after a prolonged drop in output current (even if you return to the same load condition), and to avoid confusing users, the "% charge" value reported monotonically decreases (within a reasonable hysteresis range).
Thanks

Well bought this phone back in mid 2017,and because of sickness I haven't used it that much at all.
I charged the battery 11 times so far and was keeping the phone in a desk drawer.
A month ago I noticed that the phone won't turn on,so I plug the charger on and charged the battery to 100 %.
I supposed that the phone was on,I didn't turn it off,and the battery left to 0% and shutdown the phone.
I really can't say how long it was on 0% (suppose like maybe a month).
Today I noticed very bad battery results.
Batterylife with GSam Battery Monitor is around 12 h only.
Was the "bolded text" the reason that battery died or the reason was not using the phone for 2 years?
Is there a software to check the damage of the battery?
I installed accubattery pro but for some reason doesn't offer me Health status of battery.

I would give the battery a few full cycles to see it that sorts it or yes, the battery it would seem is on its last legs. I don't know what app to recommend as an alternative though. (My battery is 23 months old and still performs as it did when I brought the phone)
I would drain it to 5% (maybe 1%) then charge it to 100% (without using phone while charging) a few times.
Then see how it goes. Afterwards charge phone from 20% or 15%.
Ok.I will charge it to 100% and report you with results with duration time on battery and you tell me how bad is it
GSam Monitor:
Battery Life: 3d 19.9h (5h 26m active)
Screen On:3h 40m (1h 17m Max)
In Android: battery estimated battery life: 2d 1h
So when i had note 8 after battery replacement i installed accubattery to see how battery health was. I see 2982. Now i fully charged to 100% with fast charge about 1 week every day. So i see now 3324! But real battery capity 3300. How recharged battery? When charged via normal charged usb not fast adapter, i have fast charge and i can disabled via settings. So on another phone i charged without fast charfe so i had 2430mah when reached to 100 it dropped down to 2400mah. Because slow charged and full reached charger. Sometimes i charged until 86% so increase mah battery. But on note8 i see overchargerdd on another phone i wiped cache accubaterry so when i turned on battery to see how battery left mah shows 2572 when i insert to charge the phone . So accubattery bugs?! Now shows on a8 normal! 2410mah 79%battery left health

Yes the battery was new . When i got i installed accubattery app to see how much health left when insert new battery! Shows 98% now i charged a day about 2weeks to 100 with fast charger and without fast cable. Sometimes percent in accubatery app dropped down . But now shows 3331 mah 101%!!! I charging to 100% but the procent dont dropped down . Proceng should be down about -500mah when charged to 100. On another phone when i charged to 100% i see dropped -500mah. When i charged to 80% battery health extended! But on note8. Overcharged 3323?? Actually 3300 mah. But why shows accubattery 3323? I charged fully when i got new battery. And now still charging to 100 on every day!
My battery discharged in 10 hours with 7% brightness . Sometimes i used 4g. Screen on time 5hours a day. Normal? Nfc off ,location off. I trying with power safe mode!

Screnshoot your full charge battery capacity with aida64, we will knows exactly how much it is. Accu battery is base on observation, not directly by battery reading.
I got 600+ cycle and 3139 mAh, but still got 6-7 hour SOT usage.
