Hi!
I've made a n interesting discovery with my battery.
3 weekends i have drained my battery until it shut itselfs off, and then i have charged it up again. And now i realy can live with my HD2 battery life.
When i come home from work i have about 80% and now as i write i have 76% left at 20.44.
Before i would have about 30-40% left at this time, i have never drained my battery before to 0, so when it happens the first time i noticed a slightly improvement. So the next weekend i did the same, and this last weekend i unplugged my charger at 06.00 in the friday morning and did not charge before sunday morning at 10.00. And for me THAT's a BIG/HUGE improvement.
Glad you resolved your issues .
I've found that having any kind of TSR apps installed on the device memory instead of the storage card, has made the battery life livable on my HD2 .

Hey guys!
I really need to try this. my battery life is just so pathetic.I hope it works for me too.
TSR - Terminate and Stay Resident.
Anything like G-Alarm/G-Profile, task managers etc. Any program that stays on or runs in the background I install to the phones memory. I think there is increased battery drain caused by accessing the storage card constantly IMO, so installing stuff like the above has made battery last 48hrs no problems. I too like to do a couple of full drain and recharge cycles a month .
I'm willing to bet that the majority of people who have battery issue probably has like a **** load of apps installed and/or unaware that some of their apps that they installed were running in the background. I've had the t8585 and the newer t9193 and never had any battery issue. The battery will easily last me 50hrs with light-to-moderate usage.
i can only confirm this.
after draining ur battery a couple of times, u need to fully charge it and it lasts longer than the first few days with the HD2
from new my battery life was totally useless. would barely last until 9pm no matter what i did.
two weeks ago my phone decided to forget it's pin lock number so had no choice but to hard reset the phone. since then i get a couple of days out of it and that's with heavy texting and web browsing.
i loved the phone before but battery life drove me up the wall but now i'm getting more life out of it i am now loving the device!
On the first couple of days I had the phone I had <40% by the end of the day but now even though I use my phone alot more I find I get to bedtime with ~50%
charging it unpowered after the drain also helps. (like with USB not the charger)
Most battery "manuals" state that completely draining the battery from time to time followed by full recharge is considered "good exercise" for the batt

Not to hijack the thread, just wondering if you're the talented skin designer that created some of the BEST for Wizbar? I still use them on all my HP PDA's
Few days ago i bought my HD2, and before that i saw problems about battery life on this forum.
When i bought it I drain the battery until he died, then i left him turned off and let him recharge over night (cca 8h). In the morning I turned him on and i used him all day max...and in the end of the day battery died at 23h, again, when he was off I let him chargeing over night (cca 8h). In the morning I turned him on and used him average, at evening, 23h, the battery was on 54%, I went to sleep and in the morning (after 7 hours) the battery was 52%.
2% in 7 hourse is very good...and 50% over day. I'm ok with that

All that does for Lithium-Ion batteries is to reset the "estimated remaining charge" circuit. It wont increase the available battery life it just makes the battery report more accurately as to its remaining charge.

i use energy rom with the gtx, and my battery life is so bad. it hardly reach one day!!
when i sleep at +- 10 p.m, i have 90%
when i get back from school( as most school here don't allow mobile phone), it left at 70/60 %, i get back from school at around 2.00 pm, i don't have any program running, gprs off, running at edge, i use 2.12 radio, how can you guys achieve 2 days?

energy rom's use a lot of power. i didnt knew that untill i flashed the Anastasia rom ( link ) battery life is great and it looks better than energy imo. and it easy runs 2 days for me
I've been very annoyed at the rapid battery loss with Dutty's series of excellent ROMs.
I started from scratch and didn't install any apps to the Storage Card just to be absolutely sure. I even put the phone into Flight Mode.
Tonight I finally nailed the culprit for the huge drain (we're talking 50% in a few hours): it was a 16GB "Memory2Go" SDHC card. With the card removed, I lost just a few percent over a couple of hours.
I also don't get the same drain with an 8GB Sandisk card installed.
Any ideas on how to get the 16GB card to play nicely?

Damn, I never thought of the install location affecting battery life. But it makes sense, thanks a lot for your explanation!
Just starting a thread for battery life experience as people use the phone. Mine is pretty freakin' great right now, but I'll post some initial results after I get home later tonight. I finished charging to 100% almost 2 hours ago, and with just a bit of usage (maybe 10 minutes total screen on time) I still am at 100%. Though, we know that it sometimes takes a long time to drop from 100% to 90%.
What are other people's experiences? Please post display on time in battery stats, as that gives a good feel for how much you're actually using the phone.
Unplugged it at 6:30am with a full charge.
Took it to work, I put it in airplane mode when I'm in the building because I don't get a signal and don't want the radio searching for a signal and wasting power. GPS/Bluetooth/Wifi are all turned off. I turn the radio back on when I'm out of the building, and I'd estimate it's been on 2 hours since it was charged.
Have watched the latest episode of Family Guy and started on the latest episode of Dexter using Rock Player.
I estimate the screen has been on for about 4 hours. I can only estimate because I had to plug the phone in to transfer a file a couple hours ago which reset the stats.
I've downloaded and installed about 20-30 apps today over 3G networks.
At the current time of 3:15pm (8 hours 45 minutes since full charge), I have 30% of the battery left.
I think you're supposed to do a full charge and full discharge so the phone can "calibrate" the battery meter, which I have not done yet, but so far I'm very pleased. Puts my 2 yr old G1's battery life to shame...
Yeah it sounds decent. A bit better than my Nexus One was.
I would say it is on par with the Nexus One. Should get you through the day but you will be plugging it in at night. It is comparable to most android phones.

Without explaining a bunch of boring details, it's definitely better than my N1 so far. Charged it up right after getting it from the UPS guy today for a couple of hours while I took a nap.
We'll just have to wait and see after a few days of use, charges and discharges. Looking great so far, though!
Played around with it at the store today, came in at 3 p.m after school. The demo unit was already at 45% when I got it, surfed the web for about half an hour, downloaded an app, watched YouTube for about 5 minutes and the phone died at about 4:30.
Not really impressed, but its an Android phone. Hopefully it can be better, the good thing is that the web browser is a lot faster than my iPhone 4. That's what keeping me on returning the iPhone, and it starts up a lot faster as well. Took about 20 seconds to boot up after the phone died on me, and the rep charged it.
Definitely will be needing to charge it every night.
3 hr bike ride with music playing used about %50 of the bat. So its way better then my G1 but not as good as my Iphone 2g.
I'm getting much better battery life then I was getting on the G1....love this phone

How about someone download Battery Left widget and tell us what it says.
Will vary by user but it will be more accurate with remaining battery life.
So far the battery life on mine is terrible compared to my nexus one, and that was terrible as well.
I woke up 10am, phone on the charger, took it off, around 2pm made two phone calls. Went to work at 5pm, phone's battery was at 23% around 7pm. My nexus one around that point would be at ~50%. So far I'm not impressed with this phone, more work could have went into it.
I loaded a few webpages... did a video chat with someone on Fring for about a minute (lol), downloaded a few apps, had a few phone calls... one lasting about 10 minutes... and after being off the charger for 5 and a half hours.. i'm at 44 percent power... this is my first android device so I'm not sure if that's good or bad
Have you all that are reporting poor battery life done the full-charge/full-discharge thing to "calibrate" the battery meter. I'm not sure that it really matters, but I'm assuming it does since battery info is one of the things you can wipe in the recovery roms.
I'm still extremely pleased with my battery life.
I got the phone yesterday and played with it right out of the box till it was at 5% battery... i plugged it in lastnight and let it fully charge and i unplugged it at 6:15am this mornining... i used the gps to get to work to see how it was... i have watched videos on youtube, gone on the internet, checked and sent emails and texts, downloaded some apps... and played around with it today... i had it plugged into the computer thru usb for approx 5 min tops to set up some media files... and as of now at 3:33pm my battery is at 50%
Opening mine at 930/10pm, heavily used it to burn it to 0% and did that by 12/1230am. Charged it to 100% by 330am. Played with it a bit then went to bed, left it unplugged. Woke up today and burned it to 0% by 330pm. It's charging right now and we'll see how it goes throughout tonight. It will get a bit of pocket time so I'll get a real feel for the battery life.
Took mine off the charger at 7am throught the day had 20 incoming/outgoing calls all lasted at least 2or 3 mins each, downloaded a couple of apps, checked facebook and twitter a few times. showed it off to some friends and now it is almost 5:00 and still have 60% battery, so I am impressed especially since I had a G1 before this

They aren't changing them long enough. Lithium ion batteries don't have to be trained like the older style ones. Other other culprit could be the batterystats.bin but you can't access or delete that without root. Jut discharge the battery till it powers off and charge for 4-6 hrs.
charged mine last night while tethered to my laptop browsing - took it off about midnight
this morning the alarm sound (pre-alarm 5 minutes, full alarm for 10 mins and never woke me btw), spent about 2 hours+ talking, browsed the web for maybe 15 minutes, downloaded a few apps from the market and ran a few quadrant benchmark test - it's now almost 6:00PM and it's at 40% -
i'm happy with that - and from experience with my MT3G and the vibrant, battery life should improve with some cycling or useage

leave it on the charger for 4-6 hours after its full or just to charge it from empty to full?
I'm very glad to hear about the excellent battery life. A friend of mine has even reported his phone being on for a full day and still having battery life left.
People make sure that you charge up your battery fully before turning the phone on. It's better to be safe than sorry. I know people say it does not matter but otherwise the battery won't be accurate if you just turn it on out of the box.
10 hours and some change later after normal phone usage and I had to charge it... I'm impressed to say the least
When my phone is fully charged or has 70 or 60% remaining battery it seems to drain as normal, around 2-5% over a 10 hour or so period...
However, I've noticed once the battery decreases below 50% it drains FAST, why?
Anyone else noticed this? Test it for yourselves, monitor the TIME it takes to decrease from 100 to 50% and then from 50% to 0.
Yesterday I forgot my phone in the car whilst going to work. It was turned on however it was sitting all day in the car.
Once I returned from work I was shocked to find the phone would not turn on.
At first I thought there was a problem or some kind of fault. Once I plugged in the charger it started to charge, the battery cut and the phone automatically turned off!
I remember the phone had around 48% battery remaining, no wifi or 3g or data turned on. It was simply idling...
So the question is HOW can the battery drain from 48% to 0% over a 10 hour period without being used???
Should my battery of been ANYTHING over 50% it would only lose a few percent...
Same thing for me. (Samsung Galaxy Note N7000 - stock Android 2.3.6)
Battery slowly decreases from 100% to ~50% and then ~2x faster.
I charged the note on my computer and then switched to the charger (at ~60% of charge).
I'm no expert of battery charging etc. but just remembered my iPhone 3GS discharging faster when charged on the computer than with the charger.
If it's the same for the note, some cells could discharge faster because charged on the computer.
Can someone confirm this (or not) ?
How did you charge your phone ?

Same thing happnd with me, and charging my phone thru electric charger..
So it seems this behaviour happens to several other Note users, why?
It's a problem knowing that having around 50% left in your battery will struggle to make it through the day with little to no use...
Have you people set the wifi to turn of while the screen is off? This is unnoticeable in the daily use, but increase the batterytime massively. The setting for this is hidden, you have to push menubutton while in the wifi-settings.
Here I thought I was only imagining things about the battery life dropping faster once it has reached 49% or less.

Haha, nice to know I'm not the ONLY one facing this bug...
I can only hope Ice Cream Sandwich solves this battery drain issue.
Hmm, i think i have the same problem, but i'm not sure. Will get back to this thread when i've investigated a little bit.
This may be a typical samsung issue.
I remember when i had the spica , the battery percentage lining in kernel was totally wrong. I think its done on purpose so you would feel like you have more battery life. 75 % of the battery drains slow. And the rest 25 super fast. Can be fixed within kernel.

I believe its just a placebo effect. Battery usage always depends on so many factors its a pain to even consider starting looking for the issue.
Being on stock KK5 not rooted, i cannot report the same. I only see "fast battery drain" at the last 4-5%. If you feel its an issue, could you post the firmware version you are on and the battery stats graph just for reference?
Placebo or not its something I can definitely feel on my Galaxy Note.

When you get the chance, could you post the battery stats graph please? what we should see is a (lets say) 30 degrees angle and at about halfway it gets steeper.
I know its quite hard to demonstrate the issue, but if you lets say use wifi to browse the first 50% in text only sites and then visit youtube for the last 50%, it won't help the test.
A nice way to test it would be to charge it to 100%, then load up a long movie and repeat playing it till the battery is 2-3%. Then post the results.

When the Wifi is disconnected, the 3G scanning will get on. Isn't that defeating the purpose?

Hey there!
I would suggest to load the battery 100%, plug it out, go into recovery and wipe battery stats.
I have to admit that I don´t know exactly what this workaround does, but I read about it in another forum...and it worked for me, my battery status is much more accurate now!

I'm back. I've had the Diagnosis app running for the past hour, and i got some interesting results.
---Wiping battery stats does not help---, a full charge automatically causes battery stats reset.
I full charged mine with the electric charger after fully discharging it without turning it on.
This time i didn't notice any change in discharge speed between 100%-50% and 50%-0%.
Last time I charged the phone it was not fully discharged. Charged it from 30% to 50% then 50% to 75% on the computer, and 75% to 100% using electric charger.
It's just a supposition, but maybe doing several partial charges while using the phone makes the battery % information inaccurate (wrong battery stats?).
[Edit]In this case, wiping battery stats should show accurate battery %. [/Edit]
I had a similar problem, and I think it is to do with some incorrect scaling or measurement.
I was down to 28%, and it seemed to be draining fast even though I was not using it. I rebooted (I love how quick that is after my Arc was so slow). On restart it was at 17% ! The usage graph just did an instant drop.
I also had another occasion where it remained at 100% for 2 1/5 hours of use.
I assume some calibration issues caused the meter to read the battery wrong. I am turning off on the w/e overnight (when I do not need the alarm) to see if a slow (180 mA) charge while off will help. I may even get a decent alarm clock so I can turn the phone off at nights and charge. I spend too much time in the morning checking my email and reading news!
What is more consistent on mine is that when the battery drops to 9% or less the loss is like 1% per ~10-15% and this is with wifi/3g off, phone locked.
I'm back again. I've had some serious battery drain the last couple of days, but i noticed that Auto Sync was enabled. Once i deactivated it it got much better. Pulled the phone from the charger 9 hours ago and i'm at 90% battery left. I've sent some SMS, a few calls and that's about it, but it doesn't drain while it's in standby now, so i'm happy with it.
I am running CM10.1.3.1 with the nitest 7/20/2013 kernel and FC19 modem, on an Onite 1900 mAH battery.
I used many of the tips in this post;
http://forum.xda-developers.com/showthread.php?t=2357417
10 hours overnight with minimal usage, my battery now drops to 78% and shows 4 days 15 hours of similar usage before the battery will be drained fully. I've never, since buying the phone new, had better than 26 hours of stand-by time show up with a fully charged battery. I'm now showing 5 days.
Of course, screen usage is still the big impact, so actually using the phone drains it just as fast, but it is nice to know that, if I am not using it, I don't have to keep it plugged in all the time now.
I could be completely wrong about this but...
Have you been rebooting your phone? From what I've read rebooting the phone can throw off the battery stats. Basically the battery storage and usage is all the same its just the reporting thats off. I'm guessing battery stats get readjusted over time if the phone remains powered on.
Hello, I got my G6 about a month ago and it's been doing very well. Battery life was good, everyone was quick and snappy. Now a month later, I'm having the same issues as everyone else. When my phone is idle, it takes up about 11-22% of battery life. I usually close other apps so the Screen and Phone Idle takes up most of the battery. I will go to school with 95% charge and find it to be 70-80% after a few hours of no use. When I use it, the battery drops 10-20% per hour. For example, It was 100% this morning at 10:30am. At 12:20pm, its now 61% with only 2 hours of medium usage. I tried all the tips but battery sucks and I cant last a full day without the phone almost dying. Anything else I can do or am I just stuck with a crappy battery life? My LG G Stylo had a better battery life with only 3000 mAh...
hard resset the phone, i think u got a hiden mallware, coin miner or something, hard resset the phone!
