okay well i am one TB owner who suffers greatly from poor battery life. so bad i have 4 replacement batteries and one extended! i try to cut back on my usage to help this but its so hard, especially at work where i carry 3 spare batteries with me. now at first, Juice Defender didnt work but it recently got an update that made it work with the Tb and it works great. i used to get 6 hours top on a battery. now im getting 13+ hours with 6+ hours of awake time (i was asleep during most of the other hours). i am overclocked at 1.4MHz, running the latest BAMF rom and kernel. i have SetCPU set on conservative. Gmail pushing automatically with everything else updating every hour. Twitdroyd updating every 5 minutes and a lot of texting, games, and some music/Slacker Radio throughout the day. i think this is GREAT for me, seeing how im not used to getting this kind of time. i cant wait to test this with my extended battery to see what i get! how about you guys? have any of you guys been testing out JuiceDefender? might get some of you whiners to stop whining haha jk what are you experiences with the TB and JuiceDefender?
PS, on a side note, i never really messed with SetCPU like that but which "profile" (i guess u can call it) gives the best battery life with out sacrificing a lot of speed? i know theres smartass, ondemand, conservative, powersaver but which is best? im just curious since i never touched this
The reason JD is saving you so much battery is you have a bunch of stuff syncing. And JD is preventing it from syncing. (Twitdroyd in particular)
All JD does is turn off your data (wifi/4G) radios when the display is off. I've measured it and for me, 4G/wifi idle only pull 1/4 of a percent every hour. So in a 24 hour period I've only lost 6-8 percent from idle data.
What's your display on time?
I normally use on demand for setcpu since smartass can have issues if not coded perfectly ( I also like the control of on demand) and conservative can cause lags when there are cpu spikes.
When JD wasn't working, I started using Green Power, which has been working fine for me. Any reasons why some people think JD might be better?
BTW, one thing that seems to have helped me is to use 4G-only mode at work where I have a very strong 4G signal.
I only have one spare 1400 mAh battery and one 2750 mAh battery.

Only 8 percent? I lost over 30% within a 8 hour period with 4g on. And 11% with 4g off when idle. I have background sync off, set CPU clocked at 245 MHz when the screen is off.
Maybe I should exchange my TB?

Me? I'm in the range of 2 - 3 bars at home on 4g (mostly 2). When I'm out I get 4 bars.
I was always curious how the BatteryStats.bin works when using multiple batteries... especially if you are using a combo of standard and extended.
Does the device get confused and need recalibration? I am not sure if it would be reporting the correct battery stats to the device and may require calibration... but I honestly do not know.

Bars don't mean anything, you can have no bars and still have a full 4g/3g/1x signal. The signal db level is what matters, not bars.
My guess is that the optimizations from BAMF and the undervolted kernel combined with the smartass governor through setCPU are dramatically helping you.
There's no way that juice defender doubled your battery life with stock kernel and ROM.

That percentage is souly from the radio, not including al the other processes. I do get super good 4g signal so that probably helps my battery life
Im rooted with setcpu set to drop down to 245/368 when screen off and have Juice Defender with UJ, unplugged at 100% this morning at 7:30, its 2 now and have 88% left, texted some and had a 10 minute call over blue tooth. Stock battery.

this is what i was wondering. i decided to not try the extended battery yet for this reason. only thing that always has bugged me about JD was it messing with twitter. i would never get mention or DM notifications since it turns off the radios while the screen is off. eh a price i have to pay for a better battery

Oh okay. I misunderstood
What do you guys do to maximize your battery life? I just can't seem to get decent life. Average is probably 5 hours with heavy usage.
Any recommendations?

The usual - brightness as low as you can stand, radios not in use turned off, screen timeout 15 seconds, 200-1400 conservative governor in SetCPU.
Search AutoKiller in the market -- choose "optimal" profile, so far has given me an extra two hours today over what I got yesterday.
5h of heavy use is good already.
You can tweak your idle batt life, 2g-only, undervolted kernel, avoiding power hungry rom.
Idle battery life is just amazing with stock... just test it over night, 6hrs get 2/3% for me.
I can get 30hrs with 4hrs with screen on, the screen is the key here, i can get 5hrs with 4hrs with screen on too. ;o)

Try a kernel that is made to optimise batt life with display active, like the XTEUV92 Trinity kernel.

I tried almost every single combination of rom + kernel. And for me, pure stock has the best battery life, by far.
But i'm getting bored and should flash something... )
Ps: afaik trinity doesnt work with stock. Did it change?

See my signature, stock (rooted and removed soom Google apps) with Trinity, works together just fine
How would you define "heavy" usage?
Also, what does your "battery use" stats say? (Settings - About Phone - Battery Use)
5 hours of truly heavy usage (online gaming, for instance) is actually to be expected.

You can create a custom prl setting. Turn wifi to never sleep when you're at home... Have the prl to auto *CDMA or GSM* Which ever your network is on. (This goes to all Nexus S. users). So you have wifi on with a signal and 3g off. The phone stays in 2g for calls and uses wifi for data. Turn off google location services while your at home, turn off roaming, turn all of that off. I get about 13 hours of battery life with heavy usage. People think wifi drains your battery but it doesn't if you have mobile data turned off. When you have 3g turned on it's constantly searching for a better connection. If you have wifi on and a strong connection it isn't constantly polling.
are there any charging habits that would help prolong battery life? I usually just charge my phone every night cause, if I remember correctly, these batteries don't have a memory or anything. anyone know if that is the smartest thing to do?

I hope you don't mean overnight. I don't know if phones have auto-cutoff feature (a la laptops), but it's safer just not to charge overnight.
I personally use an extension that has a timer built-in. Nifty. Set the timer, plug the phone in, it will automatically start and stop the charging at the predetermined times. I usually time the charging to end right before I wake up, so the battery doesn't stay fully charged for too long. I heard batteries corrode faster when they're fully charged.
When my battery life starts getting shorter than usual, I let them drain until the phone turns off automatically (well I actually try not to get to that point, but seldom succeeded ), and as soon as possible charge it until full.
Usually the battery holds longer then. It has something to do with teaching the battery about the true empty and true full.. or something.....
AFAIK. CMIIW.
doesn't the nexus s have a built in cut-off feature so it will only charge to 95% though? I figure that would take care of the full charge issue. i'm also not sure if lithium ion batteries have a memory, but you could always reset the battery stats if you're on root to compensate for the whole draining and fully charging thing.

Battery stats! That's the word I was looking for No I wasn't referring to the memory effect
I don't know what would happen when the cut-off feature kicks up. My Nexus S still shows a charging icon even a while after full, so I don't wanna risk it.
The best way is by touching the charger unit after a while and see if it's warm/hot. If it is, it's still charging. But you gotta give it time to cool down first (after it's finished charging) Haven't gotten around to it, though. Always forgot to check the charger

lol, I know that my phone for sure won't charge to 100% from watching it, so even after a night of charging it's still at 95%. I've read a few explanations on this forum about the whole not fully charging thing too, so i'm pretty sure that it's like that on purpose.
What can I do to get better battery life on my Droid? Battery life seems awful. Less than 15 hours or so on normal usage.
lower the backlight to as low as you can, turn off GPS, WiFi, sound, kill some processes, go to airplane mode, dont multitask.
is there any software just 1 click to do that ?
Try Juice Defender

What for buy the phone if you can't use all these features??!!
Ok, how can I better the battery life meanwhile I can enjoy the features of my droid？
For me, I keep wifi, sync, Bluetooth on 24/7. Then put my 3g to 2g only. Turn off GPS. Let android auto setting brightness. Under the moderated use (few hours of web browsing. Calls less then 30 mins. And half an hour games) it can last one and half days. I turn on GPS and 3G only if I needed. I think besides screen they are the biggest power hunger monsters. 2G is enough to sync your data. If you pre cache your maps. It's okay to use for navigation as well. Hopefully this can help.

Increase Time between Charges:
1. Switch the vibrate function off on your phone, using just the ring tone.
The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.
2. Avoid using unnecessary features.
If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.
3. Turn off Bluetooth.
It will drain your battery very quickly.
4. Avoid using moving or animated pictures or videos for your background. Animated backgrounds will drain the battery faster.
Here are some tips to prolong the life of your battery:
1. Initialize a new battery.
New batteries should be fully charged before their first use to obtain maximum capacity.
2.Keep the battery cool.
Put the battery in the freezer or fridge. (I know it sounds weird...)
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
3.Clean the battery contacts on the battery and on the phone.

I agree with you all but this one. I do not think you need to initialize your li-ion battery. I will post a link to backup myself when I get to my PC.

When I first got my Droid X, it wouldn't last a day. What I did was to FULLY discharge the battery and FULLY charge it (not using phone during charge) and and after about 4 cycles like this, I can get about 2 days 24x7 life on the battery.

That is very interesting. I think this is about Android needs time to learn what is the real capacity of the battery. What you stated actually happens when you flash a new rom. That's also why it usually take a few days to tell the battery consumption when a new fw released.

Just use your phone as you like, and when you go to sleep, put it on the charger, so you enjoy your phone the whole day
At least, that's my trick. I use my Desire S from 6.30 till 22.30 (when i'm awake), and when i go to bed, its around 20 percent on stock ROM.
Your ROM, kernel and radio can really affect your battery life, For example, when i'm on Cyanogenmod, with CM kernel, i can use my device two days, and on the stock Sense 3.0 ROM it lasts one day. Play with these three, and see what fits you best.

Just some food for thought; sometimes limiting clocks while the screen is off is counter intuitive. If you lower the clocks, it takes the phone longer to finish what it was going to do anyways and you end up using more power to complete that operation.
I wouldn't recommend you limit the clock too much while the screen is off.
If you really want to prolong battery life look into cutting background sync activity. If you're looking to eek more beyond software tinkering you can try a kernel that allows for undervolting (such as elemental for sense roms). Might aid a little bit if your CPU can handle the undervolt.
I don't think I've seen or heard of anyone getting less than 2% drop per hour while in standby. I can get around 2%, meaning I can get around 2 days (48 hours) on a charge if I use the phone very little. I haven't heard of people getting much less than that.
I've never felt the need to underclock/undervolt. So I can't give you any tips of opinion on that. I just limit the synching (shutoff things you don't use, limit the things you do use) and things like push email. Aside from those things, standby battery use probably has more to do with battery, radio, and reception in your area than anything else.
The previous question of what battery drop you are getting now is a good one, since you've kinda mentioned what you "want" it to be, but haven't stated where you are at now. But as I said before, I don't think you will get much better than 2%/hours regardless of what you do. If you are much higher than that, maybe there is still some tweaking you can do.
I'm not too sure how to go about this, but when I try to charge my nexus 5, regardless of the cable or charger i use, it won't charge faster than 1a unless I blow into the micro USB port hard, and I'm not sure if it's dust, because if I unplug it and plug it back in again it will go back down to 1a charging, when i blow into it, it can charge as high as 1700mAh...
Sorry for the noob question, it's my first post.

He's just going through throttling which is normal. My phone does the same when battery is higher than 80%. My phone charges at 1.7A from 0-80% then 1A to 90%, then 0.6A to 100%. It's all pre dictated by the onboard battery chip

Yeah true, I find the estimation by current widget to be alright for general current usage when comparing chargers. As long as the battery doesn't take several hours to charge, there's no need to be concerned
It was below 80%, and i realize that current estimates aren't 100% accurate but I don't think they would be 600mah different to the original...
I'm using battery monitor widget, I'll post screenshots when my battery drops to about 70%.
I'm not sure if my micro USB port is faulty or maybe it's just dusty, even though it doesn't look dusty, does anyone else have this same issue?

Haha, which fittingly has been described by Nintendo to be a placebo effect. If you just took the cartridge out and placed it back in, apparently that had the same chance of working.
I think the same can be said for this situation.
OP, mA current as reported by Android jumps all over the place. I could take a screenshot of it showing 1600mA, 1000mA and 600mA all within 20 seconds of each other. The only thing that you can do to try and prove this is happening (which I seriously doubt) is to use a log to plot the charging level over time. Even then the results could be skewed by whatever the phone happens to be doing during that time.

This was with the stock 1.2A charger. It's actually just my phone's usage constantly changing that causes the spikes, if logs were able to update more than once per second it would be jumping even more as I'm able to see with manual refresh. This happens during charging, full load and idle situations but your issue might have had something to do with the USB fast charge settings in certain ROMs.
I find the 2300mAh battery can be pushed surprisingly far, depending on your usage. If you're willing to sacrifice certain settings it can make things easier. This is on stock and unrooted, 20% brightness. I disabled Locations, Auto Syncs only allowed periodically at preset times, and used apps that are fairly battery efficient.
That was mostly WiFi, but this was with more mobile usage. Two work days on a weak 3G signal, 40% brightness using mostly Hangouts, Feedly, and 2 hours of video. Check out the [Battery Life Help] thread for more tips.
That's pretty impressive, i usually get about 3 hours SoT, with a bit under an hour phone calls usually and occasional snapchat, usually just internet browsing, underclocked to 1.7 and i almost half an hour SoT improvement without any loss to performance, cause i don't use my phone for gaming...
