OK, I know battery life is always an issue with PDA phones. I'm never far from a charger. I'm fine as long as I'm just checking e-mail (4 accounts, once an hour) and a little light web surfing with Opera Mini.
The problem arises when I use my phone as...well...a phone.
My Tilt loses battery power at an alarming rate when I'm talking on the phone. A 20 minute conversation will easily cost me 40% of my battery.
I'm usually in a non-3G area, so I'm on Edge. I normally have a good, strong 4-bar signal. Even when I'm in a 3G area, I use a different comm manager to turn off 3G to conserve power. I use KaiserTweak and select all the "Advised" settings in the power-related sections.
I've tried several different radios, but haven't noticed an improvement.
Does anyone have any ideas or recommendations on improving the efficiency of my Tilt in phone mode?
I have the same problem.
I have 3 batteries. 2 Samsungs and 1 Dynapak. Each battery lasts about 3 hours in standby. The phone is always warm as well. I have a utility that shows the phone is running around 380mAh current. That's seems pretty high.
I think theres something seriously wrong with certain batches of these phones.
these phones r seriously poor for battery life.. i love the htc but they slowly being overttaken by other phones.. shame!
maybe depends on the battery and ROM/radio because my Kaiser lasts 1 gay of VERY heavy usage+calling, and in stand by can lasts 6 days at least.

Really??
So, what battery are you using? Which ROM? Which radio?

mine too or maybe more. Normally I charge every 2 days.
Seriously though, hasn't this topic been beat to death with a stylus?
Ask youself this, how is your battery and what all is running on the phone?
If the battery is a year old then just accept that it's shelf life is over with. If your phone is always warm that would general mean that one of the radios is running, Wifi , data, gps? If any of those are running all of the time or when you are not using it, then your draining the battery.
I have a friend that beat himself up trying to figure out why his battery would drain so fast, he reflashed the phone 3 times a day etc etc etc. He just could not accept that it was a crappy battery. I got another (used battery) and it worked fine.

Me too used to get about 2 days with a 2700 that is being registered correctly, i now tell everyone to not phone me "well they don't listen just like no one does" so i block all incoming calls with MagiCall, to what point do i have a phone now? To flash & twaek and text
"Am kinda joking but my stylus is now half the size due to this topic"
Buy a new battery.
I don't dig long phone calls unless there is something going on. Too many people just want to hang out on the phone and say nothing.

This isn't my first foray into these HTC devices. I've been using them for nearly 2 years now, and I know the battery life on these devices isn't what it is on something like my old RAZR. I'm just fine with that; since the Tilt does so much more, I don't expect the charge to last a week like my RAZR did. But this drain while using the phone is driving me nuts.
FYI, I know to keep WiFi and GPS off, and to use KaiserTweak to shut down data connections when they're not being used. If I don't use the phone or surf, the battery will easily last me 2 days, and that's with checking 4 e-mail accounts every hour, and with SBSH PocketWeather getting updates every 2 hours. But talk on the phone, and it's a different story. I talked to my wife for about 30 minutes last night and went from 80% to 20% battery level.
The battery is only about 7-8 months old. Still, I ordered a new 1600ma battery last week, and it should be here in a day or two. I'm hoping that solves the problem.
It's possible that the battery you have now is under warranty. (if you bought the phone new)
good luck.

Unfortunately, it was a refurb, and the warranty expired a long time ago. The new battery wasn't exactly a budget killer.
Well my battery seems to be working now.
Phone is no longer hot all the time, and my utility says I'm using between 1 and 64 mA. That's much better than the 350+ mA it was sucking before.
I didn't do a damn thing different either. Didn't change any settings for the radios, didn't reflash, etc..
Some people think that the GPS get's stuck in the "on" position and there's no way to turn it off, short of opening and closing GPS Aware programs repeatedly until your current usage drops in the sub 100 mA range.
Always discharge your battery fully as possible at least 1 a week to ensure your battery last longer, lots of charges above the threshold will diminish your batteries life and capacity. The Kaiser is a powerful device and it is obvious to anyone that this requires power to run it, so the battery wont last for days. :-(

HUH???????
These are Lithium batteries, we aren't in the 90's anymore buddy.. My phone lasts for at least 2 days and sometimes 3 (the phone is over a year old too)..
Welcome to the year 2009
"1. Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half.
Problem is battery memory doesn’t apply to Lithium batteries, this advice was meant for Nickel based batteries. Fully discharging your Lithium battery frequently can actually be quite harmful to your battery’s health, possibly rendering it completely unusable if energy levels go too low.
The good news is today’s lithium batteries have a safety circuit in place to insure the battery doesn’t reach the point of no return. The safety circuit isn’t fool proof of course, if you leave your battery completely drained for a few days, even the circuit’s protective measures won’t save it.
"
INFACT it's recommended to leave a little bit of a charge before charging or storing.
l o l
Be that as it may, when you get a new battery you still have to use it for a few weeks before the phone reports battery levels accurately. The phone may still shut down when WM thinks it's almost empty, regardless if it's actually empty or not. Just try it, battery life improves over the first few weeks of usage, and your battery level readings will get more stable (instead of dropping to 50% in 10 minutes and then proceeding to stay there for 6 hours).
BTW my kaiser lasts about 3 days as well, with fairly heavy usage.
No fair, I want a bazillion stars next to my name too.
I Think this guy has had the phone and battery for a little while, so the few weeks thing might not be an option. (well at least the battery he was posting about)

As refered to your reply, i didnt mean discharge fully completely i meant the cut off point would stop you anyhow, i meant to bring it to about 10%, i found that using the battery until it reaches 10-12% far by decreases battery drain when it is fully charged again, this is only 1 in a while though not frequently. I understand lithuim-ion doesnt have a memory effect problem, but there is such thing as variable current influencing different cells which can either benefit or make it worst, there is a lot of debate as to whether this improves it or not.
Great tip, keep it cool and away from your pocket pants because heat kills it.
Dude thats no fun to keep it out of your pocket,
I turn my phone on Airplane mode and unplug at night while I'm sleeping.
BUT! When at work and at home at other times, is it bad to leave it plugged in 100% of the time? (I.E. does it decrease total battery life over a few years to be constantly charging.)
Or is it better to unplug ASAP when it hits 100% and let it drop to 20-30% and recharge-unplug-recharge-unplug etc? (If so, how much of a difference would this make?)
And does it matter USB vs AC source? I know USB is half the amps, so this could have an effect too?
Honestly, the battery is going to deteriorate a bit either way over a year time span. It is probably best if you just replace the battery every year.

Doesn't matter. All you need to really be worried about is that you leave it on the charger long enough to get a true 100% charge, and you don't always put it on when at 80%, try and run it down from time to time to 10% type thing.
If you leave it on the charger 24/7 for a year, it will have no real effect on the battery that a year of use wouldn't do, and you might actually come out ahead since battery life times are based on charge cycles... when on charger, as you are asking about, there would be virtually no charge cycles.

Ooooh, interesting... Did not know that. I thought that leaving it charging was the worst case possible.
But let's be honest.
How long do you think you'll keep the phone?
I've never had one more than a year...

[Edit]: Well, my thinking is how BAD could this affect it. Like leaving it plugged in all the time = 50% battery capacity in 4 months type of thing. I guess that is not the case though eh?

To add to what pjcforpres said, I would suggest topping off the battery a couple times a day rather than always letting it run down to 20-30% (deep cycling) the battery. Deep cycling is worse for Li-ion batteries. It causes more heat for longer periods of time when you do charge. I would only discharge completely once every few months to keep the battery calibrated.
My personal habit is to top off frequently. If I'm at home, I'll let it charge to a true 100%, like pjc said, then take it off the charger and leave it off till it hits 75-80% and top it off again.
i can add to this discussion what i've learned about lithium-ion batterys
having it plugged in, while it is being taxed heavily (playing games) and already at 100% is a bad idea, then i discharges and recharges all over the time.
When it isn't full and you plug it in to top it off it shouldn't really do any harm, as long as you disconnect it when it's at 100%.
Emptying it completely also lowers overall capacity, 10% is a good threshold when to charge it.
When leaving it off to store it for a while, store it with around 70-75% in the battery. Storing it fully charged also lets capacity down.

I respectfully disagree with creepinshadow's suggestions. I've read up on lithium ion batteries considerably in the last few years. 10% is not a good threshold to always charge your battery from... that's deep cycling and was great for nickel metal hydride, but isn't good for lithium ion. That said, there's no way for it not to get that low from time to time if you're away from your charger for extended periods and I'm sure it's not going to destroy your battery as fast as one might think.
As for storage, the I charge (or discharge) mine to 40-45% then pop it into the fridge for storage. Read that in a long article explaining how to treat li-ion batteries.
Like you said though, a full discharge for calibration is running it till it turns off then plugging it in while keeping it off until an hour or so after the light turns green.
I've heard many people say that leaving any device that has a battery plugged in won't harm it as long as you're consistant with the charge cycles. Like only plug in your phone when the battery life is >15% and charge it to 100% before unplugging it.
I get into trouble there, because (for instance) say I'm going to be going into the mall for a while and my battery is at 30% and it's going to take me 30 minutes to get the mall (I live in Northern Virginia, traffic is a *****, haha). I'll hook up my phone while I'm in the car just to have extra battery life while I'm away from a charger.
good question, i wanted to know the exact same thing so good to see someone else ask. got the answers i needed.
Look guys... the reality is that this discussion is really just academic. Take my recommendations, for example. It would be ideal if everyone could do what the study I read suggested, but it's not practicable to always top off the battery and not deep cycle the battery frequently. That being said, I'm sure the difference in battery life wouldn't be apparent for a very long time. I can't imagine phone and battery manufacturers haven't thought about this. So...while I've posted my "recommendations" based on that study... just enjoy your phones.
A new battery cost <$50 i'm sure... If you left your phone plugged in over night, every night for a year it probably won't hold a charge better than someone that unplugs in once it reaches 100%..
I personally would rather not deal with always worrying about over charging it and IF i still had the phone when the battery needs to be replaced, just replace it.
In the past 16 months i've had the Touch Pro, Palm Treo Pro, BB Bold & now the N1.. so i never have a phone long enough to even care lol.
I guess that's true. We can always replace the battery, unlike the Fruit people!
But I was just worried that the damage happened quickly. But I guess it's 9-12 months before seeing any real effects anyway.

My phone dies so quickly it's not even funny. ~20% in 1 hr even after just barely using it.

- Bought it second hand, but I've had it for about 4 months.
Should I get a new OEM battery? or is this just normal?

Get CurrentWidget from the market and see how man mAh it's using, even when the screen's off. Can help diagnose the issue more clearly then.

yes you need a new battery. on android my battery lasts from 24-36 hours depending on how much I use the phone.
wrap it up so no moisture can get in then put it in deep freeze over night or 24h, take it out and then let it thaw at room temp and then charge to full.
In some cases this will work and has worked for me on a laptop battery and a phone I had a few years back. They used to die after a hour or so and then after freezing they was back to normal for a good while.
If it works or you get a new battery always make sure never to put it on charge unless its nearly dead, ie 1-5% or max of 10%. If you keep on putting batteries on charge when they are not dead this f*cks them up as some battery types have a sort of memory.

Those actually sound normal. What you should do is check how much juice the battery is retaining. Let it charge fully - charge until current widget is reporting single digit charge. Use spare parts to check the battery information. If it's significantly less than 4200mv at full charge then try to wipe the batterystats.bin from /data/system, reboot and charge again. If it's still very low voltage then you need a new battery.

I always wipe batterystats when flashing a new rom, and it's pretty much at 4.2 - 4.22 at full charge
My sd android builds will last 24-36 hours if I don't hardly use it and keep it on standby... that's with getting 4-6ma drain. If I use it, though, it will only last 4-6 hour of straight use, depending on what you're doing. That's with 150-350ma drain during use. So with normal use I can usually make it through a 12-18hr day before charging. I usually carry a spare battery with me just in case though.
Normally, Li-ion batteries life-span is around 300 charges before they start degrading and not holding a charge as well... so if the battery has been used a year, it's probably time for a new battery.
I think this is a great topic. My battery uses about ~350 mA on just browsing internet, and dies within several hours (about 3). At 100% charge it says 4202 mV in spare parts, but dropped to 99% and 4138 mV within next minute. In another nibute it dropped to 98% and 4108 mV. It means battery not holding charge well? Stats were wiped before flashing

Three hours of browsing is not bad - but three hours of continuous screen turned on is a sure battery killer. Have you set your screen to a dim setting, or is it bright?
My battery dies very quickly too, about 4 hours on Android, with heavy usage, and about 2 hours on WP7
I have the official extended battery, though, and also the Cheap Chinese one, so i have backup

Depends. I often keep it on auto. The place I work has very bright lights. I read a lot about HD2 Before I got it. Powerful phone with a tiny battery. On the stand by it actually isnt bad. Eats about less than 1% per hour. With little use, texts and calls, it can last quite a long time. I asume my battery is fine.
What is your mV reading at 100% and less than that?

Not true man. On NiMH rechargable batteries (those are really old - I've never actually seen them in phones although I'm sure they were used sometimes... I still see some AA batteries of that kind laying around though) have a memory effect and get screwed if you charge them without depleting the battery life first.
However, we have Li-Io batteries - which, although there's been a lot of controversy, it is basically agreed upon that either it doesn't matter when it's charged or it is actually better NOT to fully discharge (except for around once a month in order to calibrate the battery).
But the freezing the battery thing is pretty cool! I have to try that on a friend's laptop battery that got screwed up!
that is way beyond normal. change your build.

Have done (flash one every couple of days), and still the same problem, also tried what TheAthiest said, but didn't make a dent.
Would Task29 make a difference for this person? Just throwing that out there
Or do I need to let it die completely before charging? What do I need to do?

use it fully untill it drains completely, then charge it to 100% , then use it fully 2 or 3 times and fully charge it.
then just use it like normal and charge like normal

Please do not follow this advice. This used to be the best way to stop NiCad batteried from developing low capacity 'crystal memory' but it is not the case with LiOn or LiPo batteries, in fact, quite the opposite. Doing as he recommends is much more likely to damage the battery and even start a fire.
A LiPo shouldn't be discharged by more than 80% if at all possible. If you want to know more there are a lot of links on the interweb but here's a typical thread on stack exchange .. and a quote from it ...
http://android.stackexchange.com/qu...-first-time-charging-on-li-ion-batteries-myth
Nowadays, batteries are often Lithium-Ion or Lithium-Polymer and such batteries (as I have read many times and based on my own experience) would be stronger if you charge them often. The first time charging and "wait-until-full-discharge-before-recharge" and "don't-use-when-charging" are not applicable to these modern batteries.
Li-Ion and Li-Polymer batteries, if charged often, after about 1 month, would reach to their maximum performance, and you are recommended to charge them every time you find an outlet!

Wow, now we have the Richard Dawkins of battery advice. Well done.
Can everybody just calm the funk down and charge their batteries as and when they see fit? It's fine. Either way.
There is circuitry inside the battery that will prevent them from over charging, under charging, over discharging catching fire and generally behaving badly. There is also no memory effect. Just charge them when you think you'll need them.
Yeah just keep using it, if one day in the distant or not-so-distant future it doesn't turn on for some reason and/or seems unresponsive, it might need charging.

Hmmm .. shows how out of date I can get ... I didn't realise that the overcharge protection had reached such a state of sophistication ... Personally I never bothered with battery regimes, even in the bad old NiCad days ...
Thanks for the correction.
The overcharging prevention was first introduced to the Sensation and EVO 3D phones. I remember when I started seeing it because I would leave for work, and sometimes my battery wasn't charged fully. What it was doing was charging to 100%, then stops charging and will let it discharge 5%, then start charging again. And it would keep doing it until I took it off the charger. I've yet to see my EVO 4G LTE do that, though. Maybe it's been refined so that we don't notice it as much?

Wrong. Even early smartphones had overcharging protection. My old HTC Desire definitely had it.

On the note of over-discharging: just because there is circuitry inside the battery to prevent over-discharging doesn't mean you should ever let your phone run down to (what your battery shows as) 0%. Yes, the phone will generally shut off when the battery is left at around 3v, but it's still possible to force turn your phone on (which you should never do) after that point. Not to mention, leaving the battery at a low voltage for a significant period of time WILL affect the overall lifespan of the battery. Battery manufacturers will do what they can, but there is really no such thing as "true" over-discharge protection, as with overcharge protection, since batteries will still lose charge even when not in service.
Yes, if you let your battery run down to (what your phone shows) 0% occassionally, that is OK. But you should really only be doing that if and only if you need to re-calibrate for cell mismatches.
Hah! I still remember when I bought a mugen battery the instruction clearly says to discharge it fully and charge it fully for like 5 times to get optimum capacity Obviously I didn't do it. I am much aware of these things since good old Nokia 3310 days.
I am new in HTC phones. I will get my htc one after 2 days, i mainly want to know about battery charging cycles. how can we do that to get maximum battery life. what is mean by battery calibration ? is the battery to be calibrated in every weak ? sorry for my bad english
Once at month, you have to discarghe the phone at 0%, put it in charge and switch on it when the led is green.
The battery life, during the day, depens of you and your use of phone
Just use it. Charge it when you need to, charge it when you can, top up charge is fine. Calibration is a myth. You don't need to do anything or not do anything abnormal.
Letting it run out and leaving it empty is a bad idea. Charging it, turning it off, charging it, and whatever other voodoo is recommended is a bad idea.

One charge for a day is enough for htc one if you don't play games
If you really want the most optimum battery life out of your phone then don't let it drain below 30% nor let it reach more than 90%. You'll likely get the most charge cycles and prolonged battery life with that. This suggestion sounds sarcastic but this is scientifically factual.

How many HTC one batteries did you test? Using what methodology?
The only scientific fact is that you just made up those numbers, you have no idea what charge and discharge limits have already been placed on the raw cells by the battery circuitry.

HTC One Battery Conditioning

G'day mate. When I had my HTC Desire, there was a process of conditioning that was advisable which pushed my battery life from 3/4 of a day to a full day. Having just received my HTC One last Friday (and what a magnificent phone it is too but that is a story for another day), I can honestly say that no conditioning is required (after-all, it does have a 2300mAH battery). I would suggest that you make sure that the first time you charge the phone, you leave it on charge for a minimum of 8hrs (as recommended by HTC). I left it on charge all day and I believe it does make a difference. As for making it last long, may I suggest you invest in an App called Juice Defender Ultimate (not very expensive but extremely useful) ? I am using this app and I have improved the battery life of my One from a single day to approx. 2.5 days. But I am an average user (emails, some internet, some music and blinkfeed). I don't watch movies on my phone so I am not too sure how that will affect battery life but I believe it will have some effect.
I hope this helps you with the answers you seek.
It's based on scientific facts.
When your battery has high load(Almost fully charged) more ions inside the battery are stored there hence doing alot of chemical changes in the battery. And chemical change is the only reason why our batteries here are losing it's capacity.
And the reason why I set 30% as the minimum is because you don't want your battery to be drained too much as there's likely chances that you'll completely drain it causing it to be broken also.
And why limit the examples on HTC One batteries? Is this a serious question or just a joke? We all know that HTC One was just released months ago and another obvious fact is it has a non removable battery. So obviously the answer would be none.
And about real life proofs about my usage and how it affects battery life do you want me to show you a nokia 3310 model still up and running for almost a 8 years now? Also want me to show you my nokia n900 which is already about 4 years now and still kicking it's battery perfectly up to now? I could have also showed you my n95 up and running till now if only it didn't break it's flex cable.
There's no such thing as integrated ticking time bomb on your battery(like rumors in the 20th century where they say electronic ICs have a hard coded date where they will totally shut off) where it would just instantly die once it reach it's recharge limit. What manufacturer in their right mind would do that? Smartphone business isn't a monopoly and every competitor would want the best of them all on their products. Also if this myth would have been true most people's device wouldn't even last a year due to plugging your phone on a computer would initiate a charge also. So would that mean that if I plug my phone on my PC 5x a day and charge it once a day it would only last roughly 6months? lol!
Also here's a good website that would backup my claim.

Partial and random charge is fine; does not need full charge; lower voltage limit preferred; keep battery cool.

Prevent full cycles, apply some charge after a full discharge to keep the protection circuit alive.

Keep cool, battery lasts longest when operating in mid state-of-charge of 20–80%. Prevent ultra-fast charging and high loads.

Did you read those websites? Because their numbers and yours don't agree. So either you made up the numbers or you obtained your scientific facts from elsewhere.
As much as I know....just dont overcharge and frequent charging. Overcharge meaning leaving your phone charged for long hours after it has reached 100%. Frequent charging meaning leaving your home with 100%, reach office at 85% and charge. Going for lunch with 92% and came back with 87% and you charge again. Get the picture? I'm no genius on batteries and dont bother looking up and reading on them. Just based on experience, over many phones. And yes, the first charge is very important.
I thinks the powersave is the best route when not playing any games. If you play games then you can call it quits!

As much as I know, dont drain the battery too much the first time you take it out the box. All batteries comes with a little charge in it. Had a friend who used to work at a mobile company and I cant remember the term he used to describe that. But the first charge doesnt have to be exactly 8hrs. Phone might be fully charged after 4-6hrs if you hadnt used it much from the box. Just dont unplug it before it reaches 100% on the first charge. Let it get to full and leave it for another 10-15mins and its good to go.
