Battery life with cupcake update?

I'm thinking of buying a G1, but I'm put off by all the complaints that it has horrible battery life. Does the cupcake update help this any? How long do people get?

The cupcake update hasn't been released, yet. At first, I had a HORRIBLE battery life, but after calibrating the battery, it's got a decent battery life. I haven't really taxed the phone much, though.

I know cupcake hasn't been released yet, but the code is open and people have already flashed their phone with it. So I mean, "Does cupcake (so far) help battery life?"

You can calibrate the battery all you like .... it's still really crap !
Just as well the phone is soo brilliant at everything else that it doesn't bother me!

from experience, no not really. mind you, the version we have working atm is no where near the finished version. so maybe they'll implement a better power management or something, i dunno.
thats if they ever release the damn thing

The battery just doesn't last on the G1 no matter what you do. You can extend the battery life to a couple days if it sits idle and has the right settings, but that's boring.
This phone shines through use so expect to charge it daily. If you do things like tether, stream music, web browse, constant email/texting, and etc, then I would say keep a charger handy.

I bought an extended battery (2600mAh) off ebay for about $45 and i'm a pretty heavy user with irc,music,youtube,twitter all that jazz and my battery lasts 2 days. Sure it's a little bit thicker, but it stays in a jean pocket all by it self and everything is just great.

I think The battery life increases with cupcake as i flashed the latest cupcake build (sync-ed & build yesterday by me) it usually used to go down till morning when i sleep but today it was 70% left means very much...
Also as i changed the statusbar battery icon to show 1%, 2%, ... 100% i was able to keep track of my battery...
lets see i ll stay 1 more day on cupcake and let u know...

Version 1.1 helped a lot with battery life. Most of the initial complaints were with version 1.0. Most of those initial complaints were also very shortly after the initial introduction when a lot of new units suddenly hit the market -- as with any battery device, it needs time to break in and calibrate itself. Note: cupcake is to be called version 1.5 (there will likely be no 1.2-1.4). Expect 1.5 to have better power management than 1.1, it does have a newer kernel with better power management features, and no doubt many optimizations in userland tools.

how can you calibrate the battery?

Are there battery benchmarks somewhere for 1.1? I've been googling but it's hard to find real numbers and usually they don't mention the version. How much battery life do you get?

With normal use I wouldn't expect to get more than 24hours. I reckon by switching everything off I could double that. OTOH as the phone charges via USB I just leave it charging whilst I'm working - it'd be sat on the desk anyway so the extra cable is no hardship.

By using it.

You calibrate the battery by letting the phone completely die while it is on, as in let the phone shut off because it's out of battery. Then, give it a full charge from the house charger, preferably while not using the phone (while sleeping, for example). Should be done twice a month or so for this phone.

You should know that modern batteries dont have the "memory" that old batteries do.
There is no need to do the above.

They don't have 'memory' but modern batteries still have a break in period. You'd have to probably have a solid battery like thin films to avoid that.

I know that, for example, While it takes 5 minutes of watching video for the battery to move from 10% to 5% it can take 30 minutes to move from 5% to DEAD with a non calibrated battery.
I train my battery every so often. I can get a solid 3 to 5 hours of talking/texting/browsing/downloading/playing games/etc on a single charge.
I don't think its too much to ask for. It's in line with other phones of like capabilities. Upfront people were just pissed that they couldn't sit and play on their G1 for 10 hours a day with no charging in between.
You can't do that with an iphone, itouch, psp, ds, portable dvd, or laptop computer. People were expecting it to perform better than all the things listed, but the only thing technological about this phone is the software. It has the same tech restrictions as every other portable device.

i thought that the new batteries nowadays do not need to be conditioned anymore? that whole break in theory was based on the old nickel based batteries. but now they no longer needed since batteries are now lithium-ion batteries that do not have that "memory state". correct me if im wrong because i always hear both arguments.

Hmm if I remember correctly the actual battery (LiCoO2) doesn't need conditioning or has a memory effect, but its the electrical component/chip that tracks the capacity and over time though repeated charging they tend to "forget" the actual capacity of the battery so you need to drain it completely then charge it completely so it re-learns it again.

Need the lowdown on Battery Replacement

I have an unrooted N1 with latest 2.3.4. Device is a year old and I believe my battery is getting tired. In spite of various battery life techniques and apps, many days it doesn't last through the day, and have it die at inopportune moments. I need to come up with a battery strategy. I googled on this and it's pretty inconclusive. I'm open to buying a direct replacement battery, an OEM flavor of some sort, an extended life battery, or one of the expensive 3200mh batteries that require a replacement cover.
I'm also open to rooting the device if that would allow me to regulate the battery better.
I'm looking for practical advice.

Im wondering this to if its the hardware of an htc or the android os that its lacking the optimized efficieny of the outcome which in fact derailing its competiton comparison to an iphones battery use. I was eagered to grasp an android phone when noticing a huge decline in web browsing or scrolling compared to my outdated ios as of now am missing its quality structure it had possesed.

i suggest getting the stock battery, or going with an aftermarket thru seido or mugen. yes there are cheaper knockoffs, but they dont always work well.
the link in my sig is a project we did for nexus one batterys where we were able to crack open the chip inside your batt and re-programm it for increased capacity.
this let us test every battery we could get our hands on. the cheap batterys have the chip inside that is "locked" and doesnt work right. the better batteries have the fully working chip.
inside the chip is a parameter called "age scalar" which counts down with each charge. after this gets down to 80% your battery is considered dead. if you root you can use the app to check your age etc and configure your batt. either way i would stick with the known brands.

Your have opinions on the Mugen Extended life battery (the one with the alternate back cover)? I would love to not have to think about my battery...

yes my opinion is its a very good option. the 3400 mAh truly has the claimed capacity according to what we pulled from the chip in that one, plus the people using it experience the full capacity range. its worth the purchase if that's what you want, you cant go wrong.

A kind person @ HTC is hooking me with a replacement battery. It will be interesting to see how much better a fresh battery does in my device. After considering the various options of extending a charge, I've decided to be an external USB battery charger device from Trent (http://www.amazon.com/New-Trent-IMP500-External-Blackberry/dp/B0013G8PTS). Since I'm almost carrying some sort of bag, no issue stashing this device and carrying it with me for those times when I need extra juice. I will report on performance of that device.

If you are open to rooting, many times a custom ROM and kernel can provide you with significant battery improvements.
In the nightly threads for CyanogenMod (nightlies are test builds and CyanogenMod is one of the more popular 3rd-party ROMs), people have said that with the latest nightlies and a custom kernel by RedStar, they are getting less than 1% per hour battery drain when the phone is idle.
My phone running the nightlies (although the stock kernel that comes with CM), I consistently get between 18-20 hours of use unless I do some crazy battery intensive things. If I hardly use the phone at all, I can easily get two days out of the battery (although I don't do this much). And this is with my battery age at 82% (it is getting close to the official "dead" part).
Plus there are a lot of cool features that are in some custom ROMs.

Did you call HTC? if so what number did you call? I need a new battery as well and have heard that the oem ones are the best bet.

@chrisonline1991 Called main HTC #s list here: http://www.htc.com/www/support/nexusone/ If you are under warranty, they will likely send you a new battery. I am out of warranty....calling them led to a dead end.

The age is read from the chip inside your specific battery and our app can pull that value.

Be sure to get a real OEM battery or one from a trusted manufacturer. I got a battery on eBay that was sold as OEM and looks like OEM but the chip did not work and the battery life was terrible. I'm not sure what the chip does but I can confirm that having a working one is required to get good battery life. My new battery with broken chip was giving about 8-10 hours of battery life before hitting the 15% warning. My over 1 year old battery with working chip lasts 16+ hours with room to spare.
I recently started testing ch33ybutt's SS4N1 script. I am running the default settings and yesterday after 19 hours i still had 34% remaining when I hooked up the charger before bed.
I use my phone with auto-brightness, bluetooth on, GPS on, and 3G enabled. I turn on/off WiFi as desired but don't leave it on all the time since I'm really only around a hotspot at home. I am definitely not playing around with settings to save battery. Which is great because I don't want to have to mess with that or always be on the look-out for a charger.

Also a subject I haven't mastered yet. But I do know ebay is a very misleading source when it comes to batteries

Just got Sensation.. need to condition battery?

I just got the Sensation, loving it so far... it came with ~ 40% battery so I'm charging it for the first time now, is there anything special I have to do? Leave it charged for a certain amount of time? Does it hurt if I don't charge it all the way to 100% the first time?
Also, what's the easiest way to tell which panel (Sharp or AUO) LCD screen I have?
thanks!

There's a lot of ways people say. I have tried several and went from the way I use to do them. I have a replacement atm and its charging fully with the phone off.
I use to - charge - kill - charge - kill - then use it however. I've never had battery problems before with all the years of doing this method. I try the ways here and now I have them. I'll stick to my original from now on.

Personally, Just do a full charge when you go to bed. Wait for S-OFF. Flash a more optimized ROM, (Hopefully we will see Cyanogenmod 7). People are all really tedious about this whole battery thing. Li-Ion battery's are wonderful. Just use it. and When you see your battery in the red. Charge it.

these batteries do not need to be conditioned... In fact deep cyling is bad for them.

Exactly, lithium ion batts don't need any special treatment or even an initial charge. A battery calibration every once in a while or with a new ROM is a good idea but that's a software issue not the battery itself.

great, thanks for the responses guys

Conditioning is misunderstood for building battery stats. While li-ion batteries don't need conditioning, phone DOES need to build battery stats. It doesn't matter how you do it with first charge, but DO run phone through a few full 0-100-0 cycles. It builds correct stats.

Just charge it and use it. As most of the guys above said, these batteries do not need any conditioning. What people are referring to when they say battery conditioning, is the OS's battery meter. The OS won't always give you an accurate reading eg: saying the battery is low when it isn't, or saying the battery is fully charged when it's not.
When people flash roms, a lot of the time their battery readings will be a little off at first and people would freak out, and so started this whole battery calibration bull crap. Oh, G1, those were the days.

Battery Calibration Debunked (By Actual Google Android Dev)

Dianne Hackborn - 6:42 PM - Public Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it for away.

Is that what wipe battery stats does? I have never noticed any difference when I did that. To think of all the times I have run the battery down, cleared the stats, charged it, and cleared the stats again with no noticeable results.
Sometimes it seems like the battery life gets thrown off by flashing a new rom. It isn't necessarily getting worse battery life but the indicator will work funny like it will show 99% for 3 hours and I will think I am getting great battery life and then go to 30 in the next 20 minutes. It is like the UI gets confused. My tablet will sometimes say "connect your charger" even though the battery and indicator are 100%.
I don't think people realize how much drain the display is on the battery. They flash a cool rom and use it a lot and then think they are getting bad battery life because the display has been on for two hours while they play with it. It is amazing the amount of difference I get between when I am fidgeting with my phone while I am at work (have to recharge during the day) and when I am at home on the weekend and it sits on the kitchen table most of the time (it will generally go all weekend without a charge).

Wonder why its even an option to wipe battery stats with apps or recovery if it doesnt do anything. I never saw a difference myself, I just wiped them periodically cause others seemed to think it made a difference.

First of all those of us who actually knows about Android OS really knows that /data/system/batterystats.bin is nothing more than stats audit. Now if you think you can't actually re-calibrate battery and project that data than your a fool. It has nothing to do with that file.
First of all to accurately predicate it you need a true daemon that's capable of tracking system data with full autonomy access. Second you need correct battery specs from the manufacturer. As reading memory from it may or not even be supported by the device kernel if its not allocated. Thus you see issues with cross link batteries on stock roms, but some is exceptional with similar size, specs.
Now to project the correct data from ~1-100% you need to fully discharge for it to cycle. Yes I know some of you maybe saying never fully discharge Li-Io but if you know the min mV rating then you can stop near suggested mV as it won't go below and damage cells. From then the duration of full charge is defined along with total available mAh. By calculating discharged -mA draw pre scale unit over empty estimation you can predict the true battery percentage.
Ex: ATM my uptime is 14h 47m at 65% with moderate usage (talk, txt, web). Since I have MP1650mAh battery I'm currently at 1072mAh. As its drawing -90mA per scale unit with 4156mV. At this current rate fully projected empty estimation is 9h 38m. Keep in mind my deviceis highly optimized and is on very aggressive battery saving mode.

Ok, so, if wiping battery stats is useless because it does NOTHING to the battery, is there a way to address the battery and force it to allow a slight overcharge on a regular basis, thereby shutting charging off at a higher capacity?
Please forgive my ignorance gentleman, and refrain from verbally bashing me.
I bought a 1550 mAh Anker battery. If I charge it to 100% and then use it, it stays at 100% for hours. Is this because my phone is waiting for it to drop below 1400 mAh, or what? If that's the case can I somehow tell my phone to consider 1550 mAh 100%?
I ask because of the mugen power app on the market. It intrigued me. Though there is a chance its a bunch.of balogna.

That is THE prime reason people "wipe batterystats.bin" thinking it would fix staying for hours at 100% delay and heavy drop in short time. Which is sign of missing true data. Normally its measured via min/max mV and available mAh. Now by subtracting the used mA per scale unit the empty estimation is calculated. Thus projecting power draw at given duration and near accurate battery metter.

Yes, of course it is the prime reason. My question was, is there a way to tell the phone that 1550 is 100% or do I just deal with inaccurate monitoring that is based on a 1400 mAh battery?
Or, alternatively, will android figure it out over time and adjust for me?

Before battery calibration, regardless of what happens, I was getting 9 hours, light usage. After battery calibration I get 19 hours, medium use. I'll stick with it with my thick headed self.

In short: I think your battery is fine.
In long: Batteries are incredibly complex units, with slight allowable tolerances on the actual total mAh charge the battery can hold. I don't know the tolerances these batteries are built to, but they are not exactly 2300 mAh. I don't use the app you took a screen-shot of and the numbers aren't explained, so they mean nothing to me. I have no idea what they are trying to tell me, though I could make some assumptions that are probably wrong to some extent.
Also, an important thing to remember about lithium batteries is they do not tolerate a full discharge. This will damage the battery (irreparably). OEM's implement a floor at somewhere around 5-10% battery charge to prevent the consumer from either accidentally or intentionally fully discharging the battery. This is why the device will boot up on a low battery (after low battery shutdown). But it will immediately initiate shutdown again to prevent battery damage (or at least limit it). There is a great thread about lithium batteries in phones here: http://forum.xda-developers.com/showthread.php?t=1168036. The point I'm making here is that app will never show a complete 2300 mAh of battery usage because the batteries circuitry will not allow it. So, if I understand that apps numbers correctly your battery capacity is probably ok.
Keep in mind this post was by a 3rd party and not a battery engineer, but most of the advice is pretty sound (I'm not a battery engineer either, but I am a Mechanical Engineer and most of his comments pass a sanity check).

Thanks for the long reply. I'm puzzled by this really because my SOT is barely 2.5 hours on a good day. I currently lack a SIM (waiting on one) and I have been just using airplane mode with WiFi on. My drain with screen off is somewhere around 2%. I am running M rooted with elementalx and I have a -50mv under clock across the board. I'm also using the conservative governor at the moment. I have greenified everything except Facebook and my last power cycle only showed the screen, system and WiFi as the only things consuming battery. My screen brightness is cranked way down. On battery I can pretty much see it dropping at a rate of 30%/hr with the screen on. If I under clock to 1.2ghz I get closer to 20%/hr. Currently I can't even get through a 16 hour day with light usage. I'm reading consistent reports of 4-5 hour SOTs with some power conservation and frankly I don't know what more I could do other than under clock to 500mhz which I must say us pretty laggy. Yeah I know draining to 0 is bad, but it looks like I don't have much choice right now or I could just leave it on charge all day. Awesome. I think I should try swapping the battery. My current problem is finding a good source for a genuine oem battery.

I think this is the worst battery life I've ever had from a phone. I'm pretty sure my G1 was nowhere near this bad but I do remember eventually moving to an extended battery.
