there are alot of mixed opinions on how to properly train a brand new battery, I'm talking right out the box 5 mins ago. Some are saying let the new battery drain and then start the charging/discharging and some are saying charge it right out of the box.
Anybody have a definite answer that has worked for them? Battery life has been an issue for me in the past and i wanna get this one right. thanks guys!
I charge it right out the box then do a full discharge and charge it back up again.
I think I'm a moderate / heavy user and I still get quite good battery life. Averaging around 20 hours before I need to charge.

It's Lithium Ion. You don't need to train it.
Android however needs to figure out how long it can run before the battery is dead. Charge it til it's full and run it down. Do that a few times and the OS should get a pretty good idea on where the battery is sitting.

yeah sorry for not being more clear, this is what I meant. not training the battery itself but the system so the battery stats are more precise
Wasn't there a special HTC-approved charging strategy that supposedly improves battery life dramatically? Was that ever debunked as BS?

you are not a heavy user then. I got about 12 hours with 2G only selected for most of the day. switched to HSPA. hspa+ 8megs killlllz my battery. I went from 70% to about 30 within a few hours just sitting in HSPA+ area and browsing and checking emails and facebooking. at about 12:30 that night i was at about 15%

You need to delete batterystats.bin from system if you get inaccurate readings. And yes, lithium ion batteries need no training. That was the older type nickel-whatever...

So, you're basically saying we need to train the OS, not the battery, am I right?
I always gave the battery a full charge and then let it go down to 0 and finally power down before re-charging. After doing that a few times I just did whatever as far as charging goes.
I also used to charge a lot here and there through out the day. I know only charge when it's low and I know I am doing a full charge. Not sure if it makes a difference with battery health, but I feel like I notice a difference.

Lithium Ion batteries should not have complete discharge cycles. Keep it above 40% when you can. Charge it regularly.
http://www.batteryuniversity.com/parttwo-34.htm
well I did the Evo trick and... i'm at 12 hours off the charge and 34%... that's with web browsing, texting, gtalk, phone calls, etc.
I think the GSM Auto (PRL) has helped a bit as my "time without a signal" went from 44% to 0%.
There are too many different answers from discharge at half, charge to full then discharge, and not let it discharge below 40%.
I think we should all test and log the different techniques.
So far
44 hours with light use
21 hours with normal use
15 hours with heavy use
and what I did was discharge at half and fully charge, also I dont let it shut down by itself and turn it off at 1 %.

Okay, I read the post and did the evo trick, from my understand it stops your phone from constantly looking for a network.
while I made the changes, am I suppose to have "use only 2G network" check or unchecked? Also my connection changes from E to H all the time with this trick, is that suppose to happen because from my understanding it should stop it from switching networks?
I just tried the GSM Auto (PRL) evo trick.. now to wait and see if this helps at all..
Whoops, I didn't mean to imply that the evo trick was the GSM Auto (PRL) setting... I was talking about this:
To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.

My batter seems to go from 100% to 85% every day in a very quick manner. However, after that, it slows down. Maybe it is just the behavior of this battery (or the software that measures it).
Regardless, even with that, I get 12-14 hours (with moderate usage) before I get the 15% warning.

If you're running a 2.1 ROM:
Don't forget to change the Network Mode to "CDMA Auto (PRL)". Do this by dialing "*#*#4636#*#*", and then pressing Phone Information. Even if it is already set to CDMA Auto (PRL), press it anyway.
Try using a 2.1 with a tweaked memkiller. It'll help to kill off apps that are still running and using battery. I usually get about 2 days of battery out of my phone while using TrevE's MOD.
I think the battery discharge curve that dictates battery level is off in the 85-100% range on these phones.

i used to only make it 6 hours on one battery. but then yesterday we found a new setting which i can now go 12.5 hours yesterday without even trying hard. go to *#*#4636#*#* and change to GSM Auto (PRL), this more than doubled my battery life. and you do not lose 3G, the phone will still use 3G just like normal. try it out.

I don't think I use it out of the norm. I check my phone when it notifies me of messages, come on this xda app and sometimes browse the web.... it's not like I'm streaming music, playing games or anything else a lot.
i too have found my phone dead in the morning when before going to bed was at 65% full. im still wondering the best settings for home and travel before switching to gsm auto prl because i dont want to drop totally dead when going outside 3g tmobile.
i also found my wifi is always on even if sleep. after i figure out this network deal ill do something with the wifi only being on when the phone is screen on and in my home. that will prob save me tons of battery.
I run wifi constantly on, the overnight drop is around 10-15%.
It should last 14 hours if you use 100 Ma of power per hour from a 100 percent charge to 0 percent charge.
I didn't know it was possible, but with IntersectRavens kernel (or whatever his name is lol) I can actually lose 1 percent of battery life in one hour (or close to an hour).
Though without turning my mobile internet off with Juice Defender's APN widget, this wouldn't be much possible. I found this very surprising, I thought people were making false claims about this.

I should edit that post, shouldn't I.. four days would be impressive.
I'm gonna plug an app for this. It's not exactly the best thing out there in terms of an app killer (which from what I understand is a no-no anyway) but there are some nice little features that will really help narrow down some power use issues.
Do a search for SystemPanel and turn on Monitoring. It'll track when you have the phone on a charger, relative battery drain as well as device usage and cpu utilization all in separate histograms over time. History is saved (most likely in a log file) and can display from the last 2 hours to the last week. Without having to dive too deep into system settings you can track this info with just a few button presses.
I found out that using GSM Auto (PRL) and dropping the auto brightness and live wallpaper really did save a bunch as well and I was able to track the difference with the app. I also found out that playing too much Jewels will eat my battery like it was a cake at a weight watchers center.

i dont think anybody knows why or how that works. i'm still confused as to why it would even make a difference, but it DOES seem to help from my testing so far. today i am at 8 hours since unplugged, and still have 57% battery left, which is much better than i used to get. that's on pace for at least a 16-20 hour day which i would be happy if i could make it thru a day like that without having to charge.
Aren't there any explanations from Google about those settings ??
Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you
Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?
^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.
I just keep spare batteries in my pockets =D
I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.
Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.
Yea this sounds like a huge placebo effect.
Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.

Don't you mean decreased startup time?

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play
I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.
Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

Have you guys noticed any issue with the charging speed of this phone?
Last night when I went to sleep, 8PM (i know early), the battery was at 9 or 10 percent. I plugged it into the charger and all that. So this morning I go to remove the charger to check e-mail and what have you. 94%.... Come on, its 4:30 AM so that is eight and a half hours and not 100%?
Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?
Honestly, 8 hours to charge your phone does not seem right. Something is wrong with your battery. The vibrant does take a long time to fully charge, but never 8+ hours. It usually takes mine a good 3-4 hours when my battery is dead.
I highly recommend download the application juice defender. Research and learn how to use it. It will save you tons of battery.
I'm currently on my 38th hour since the last time I unplugged my phone and I still have 8% battery. Btw, I've been using my phone for phone calls, texting, and playing games.
First of all thanks for the JuiceDefender tip, that looks very promising.
But do you turn your phone off at night to charge? Because I just turned my phone off like 20-25 minutes ago and it popped it all the way to 100% just as I was typing this response.
Any other suggestions, tips, or concerns from anyone, please share.

No, I leave my phone on. Usually with Wifi too.
Also, I have a simple wallpaper that is mainly black (it has some blue designs, but the wallpaper is mostly black). Having a black wallpaper saves battery as well because the color black consumes the least of amount of energy from our screens.
Well my homescreen is pretty black. Black mesh background, black icons (bettercut). Black bar mod. Just got done configuring juicedefender, even bought the pro version. Figure if it doesn't work out I can simply return within 24h. And, I will know within 24 if it is helping the draining.
Leaving Wifi/Bluetooth/etc on will suck your battery down. Turn it on only when you need it. This is true of all smart phones.
My Vibrant will charge to full in a couple of hours from dead. I get 10+ hours on a charge even with heavy use but I almost never use Wifi or BT so YMMV. I definitely get better battery life from the Vibrant than the old G1.
Curious if you could pay attention some time when your awake... my phone rarely charges past 98%. Wondering if your phone is charging up to 94% quickly, and then hovering or if it's actually taking 8 hours to get to that point?
Maybe you should get a replacement.
I can plug my phone in around 10pm and at 6am my battery sometimes says 98-99%, but normally is good to go shortly afterwards. I do turn my phone off at night and those that need me do have my home number too unless I'm traveling.
As well I normal usage is 6am-10pm or so and I have typically 40-60% left on the battery depending on the usage. Yes I do check the About Phone and not relying on the wacked out battery meter.
I don't leave wifi, gps or 3g on all the time simply because I don't need them. Id rather squeeze the battery than have something on that isn't being used anyways. Having that quick settings drop down in the Notification bar rocks.
I have the same issue. It always takes about 4.5 -6 hours to 'fully' charge my Vibrant from <10% regardless of whether the phone is on or off. Then after unplugging the charger, the battery info states that the battery is charged to 96%. My belief is that there are firmware issues with at least some TMO Vibrant phones. I'm also dubious of the USB charger. I've ordered a regular charger and I'll see if my suspicion surrounding the USB charging system is founded. Maybe...

Mine takes about 3 hours to charge but I normally get about 13 hours a day on it with normal to serious use. I haven't had a problem with battery life since I purchased it but I have been trying new battery saving techniques to see how long I could make it last.
Currently using a mostly black background. Wifi only when I'm in the house. Brightness all the way up. Synching two email accounts and Facebook all day. Definitely getting the most out of the battery that I could expect.

(Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?

Well mine takes a while but not that long. I'm going to try out the juiceDefender that was mentioned but the other thing I would recommend is the accurate battery mods that can be found in the Themes and apps section. You can flash with clock work and it's a great way to know what your battery is actually at so you can see how much you're using for various things.
Make sure your charger or USB port has high current output. There are some out there with only a few hundred milliamps. The phone will take nearly one amp and should charge in a few hours.
Excellent point. For me, I'm using the supplied Samsung USB to 110v adapter and I'm getting 4.5-6 hour charge times.

Also the USB cable is important too. 1 amp over a long, skinny 5 volt cable can drop the voltage. If the charging chip sees a lower voltage, it will think the USB port is at capacity.
I love this phone but I must be honest.. this phone is worst as the Motorola cliq battery wise. it's terrible. I had 100 percent battery life at 8am and at 10:50am I had 23 percent battery left............ no matter what I was doing.. even if I had the screen on full blast *i had it on the lowest* it still shouldn't be almost dead in 3 hours .... smh!

One poorly written application running in the background could be causing the CPU to wake up constantly. Yet I can talk for hours and the battery will still be nearly full.
I know for sure one of the latest versions of Facebook ate batteries like crazy. I ended up installing an older version and my battery life returned.
Update on the issue. I was using juice defender but it wasn't doing anything for me as far as I could tell. I have since turned off vibrate on touch, and noises coming on during clicking. I am using a usb hub with two vibrants on it. I'll plug it into the wall tonight and see how that goes.
I have been turning off my wifi when not using it. A little better I suppose. While typing this I went from 49 to 46 percent and I am a fast typer. No wifi bluetooth gps.

Yes the battery drains pretty fast, and it does take about 3 hours to charge... my main problem is... at night when I plug in to charge, couple hours later I get woken up by a beep and popup window telling me charging is done and to unplug...
anyone know how to turn that off?
So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky
Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.
