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,
EDIT: It's here!
http://shop.htcpedia.com/index.php?dispatch=products.view&product_id=819
It appears to be OEM, and is gonna be much cheaper than the crap out now.
My main issue, what cases are gonna fit around this nicely?
I don't want it to be a fatso.. Then theres also the issue of heat, considering the larger battery and a case on top.
Thoughts?
I see at the bottom of the page they are suggesting to buy the brackettron car mount.
Does that mean the official car dock won't fit with this higher back and battery?
I really want the bigger battery, seems i'll have to get a new dock too.
Correct, the phone will be too big to fit the official car dock with a extended battery on it.
What I recommend is buying the battery and holding off on the car dock. Is the battery gonna make THAT much of a difference? Really?
It comes out on July the 6th... your post says June... just fyi
They better make a rubberized case for that thing.
Thanks for the info, but think I'll wait for the Seidio 3500mAh
Changed the month, my mistake.

After reading the thorough comparisons of OEM and aftermarket batteries in the N1 forum (by user dougie i believe?)
I thought it would be a better idea to wait for an HTC extended battery.
Save money, and guaranteed quality.
I haven't tried seidio products so I can't say they are bad, but i'd trust HTC over them anyday.

I've used their cases and extended cap batts on BlackBerries and, now, on my DINC. Probably had 6 extended caps on BlackBerrys, and their holsters are the only ones I'll use - nothing but the best quality and design.
As for the extended cap batts, they perform the way I'd expect them to. I've had not difficulties with them, nor have I experienced anything that would keep me from continuing to buy their product in the future. The only "downside" is that yes, they tend to be on the pricier side but, again, worth it. Just my opinion and experience though.
i oredered the verizon 2150 battery wounder if anyone will make cases for this monster of a battery. currently i have body glove case would like another that will work with this battery
Now you tell me about the new 3500 Mah battery.
Just got the 2150 mah from Verizon. Not able to make it through a day. So yes, I am a heavy user. I have the shut down apps. done and the check for 7 different email set to much longer intervals. Video is where the draw back begins. I am going to try and return the 2150 battery. I don't mind opting for the bigger battery if it gets me through the day.

I already have this battery it 4 days now just a little bulky on the back but its easily lasting me 2 days. Last charge was @ 7:30am on the 17th its now 11:05am on the 18th and i have 54% battery still and i noticed while i was sleeping that wifi was left on

Like with any battery, you need to condition it first. It needs to go through 3 or so full battery cycles (completely charged to completely dead) to get to its full potential. If you did not do this, then you are not getting accurate results. I received this battery Monday, and its just now getting to its full potential. I've gone 2 full days without charging on normal use and one time I just laid it all out turning bluetooth on, GPS, leaving wifi tether on (even though I wasn't always using it), had all my accounts syncing every hour, and left an irc chat open in the background and still got well over a day of use.
Lithium ion batteries don't need to be cycled this will do nothing for battery life. Nickle cadmium on the other hand does need cycling.

Dozens of members and thread posts would disagree. And mine has increased every cycle since I've got it.
I don't know about conditioning.
My first charge I got over 28 hours out of it till 14% warning came on. Then 5 more hours till it came down to 10% battery left.
GPS, WiFi always on. and over 5 hours of talk time with that first charge. Something's wrong with your situation. Check all apps.
PS. I have Task Killer, but it ONLY runs when I tell it to kill apps manually. And I manually select the app to kill each time. (easier than going into settings>applications>yada yada). ATK does not run on its own on my phone.

2nd charge on my battery.
GPS, WiFi always on
Bluetooth Off
About 1.5 hours of total talk time today.
13:01 uptime
2:49 awake time
Voice Calls 27%
Cell Standby 21%
Phone Idle 19%
Wi-Fi 13%
Android System 12%
Dialer 4%
Display 4%
67% battery left
I'm on track to gettig another 28 hours of phone being "on" till next charge, if not more.
Well just ordered one since my 1750 is not holding up like when I first got it...
Sent from my ADR6300 using Tapatalk
Ordered the 3500 Mah today and found out that Verizon will take the 2150 back as long as it is within the 30 days. I am trying the cycling and what I see happening is that the longer I own the phone the less I am looking at every item and spending time looking for Apps. This in turn means the screen is on less time and so the battery life is becoming longer.
I am pretty impressed with the 2150. After 36 hours .. comprised of slightly above moderate usage during the day time.. I got about 21% left. GPS and Bluetooth were always left on.. used navigation for about 30 mins a day.

Mkk members may disagree but it is hard to disagree with facts which in this case full discharge and recharge is considered a placebo effect. Due to the fact that "lithium-ion is memory-free in terms of performance deterioration but many batteries have fuel gauges." Aka "digital memory" what this does is reports to your phone how much estimated charge you have left.

if you do find anything contradictory to this i would be interested in reading so shoot me a pm.
Thanks!!
This thing is amazing! Last night I finally let my phone just die and charge fully. This morning I unplugged it and started using it. I actually thought it wasn't reading the battery stats correctly because it was stuck on 100%. So i started using the GPS, Bluetooth etc... Finally after 3:45 up time and 1 hour awake I dropped from 100% to 99%. I am now at 4:15 up time and 1 :15 awake and at 95% and have been listening to a podcast for the past 20 minutes.
SOOOOO much better than the stock battery.
BTW - running Skyraider 3.1 RC3 with Kingx #4 kernel. Set CPU set to 998 max and screen off to 245-384.
the first time i used it i had 90 hours up time and 17 awake. This thing is crazy!
This battery sounds incredible

I just recieved my battery from Verizon yesterday. Dumb Fedex didnt leave the note on the door so i had to wait an extra three days. Anyway i charged last night bump charged this morning which took 1.5hrs WOW. One phone call and I'm down to 99% already. I will let the battery get down to 5% then recharge and bump charge i will do this two times and see what kinda battery life i get. For the size difference it better be really good. It definetly took away the slim line look. But as much as i use my phone i hate being constantly hooked to a charger.

You can get used to the extra bulk quickly. I love this extended battery. I can use as much as I want during the day and charge at night.
I received this battery yesterday. I put it in my Incredible and it said there was like %40 of charge. I then turned my phone off and charged it for like an hour or so. I turned the phone on and saw it charged to about 97%. I sat there and watched the battery drain super fast. I mean, 1 minute it would go down like 1-3 %. I was like WTF?? I'm running CM6 and setCPU. Do you all think I need a new kernel? I was going to try a different ROM, but this battery shouldn't be draining this fast should it?
What are the proper step the charging a new battery? Does it really have to be charged for 8-12hrs? If so, I can buy a external charger and let it sit overnight.
Any thoughts?
Dude, it does that quick few % drainage no matter what you're running.
wow is all i have to say, i just got the 2150mAh, with the original battery normally i unplug @ 8am and dead by 4ish pm, it is now 1030pm i have 37% and ive been using my phone a fair amount today, this battery is amazing

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.

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?

Dunno. I don't generally check that kind of data. My phone is at 69% right now, mAh is 8694.
NRG ROM includes tBattery. This particular battery showed 12296 MaH at full power, but this is only the first discharge cycle for the battery.

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.

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
I purchased the 3500 extended battery about 4 months ago. It was a great battery. It lasted me all day & then some off a single charge. Now it's not lasting as long as it used to. I'm having to charge in the middle of the day now. I put my original OEM battery in, & I'm getting better performance from it than with the 3500 battery now.
Anyone else experiencing less than stellar performance from the 3500 battery after having it for 4 months or longer?

I have the 2150 OEM, I can only suspect some reasons why
1) Cheap battery that does not hold charges well
2) You are draining the battery down to 0% a lot, killing the ability for it to keep a charge
3) Your phone is not calibrated properly so it shows it is charged to 100% but in fact it may have only charged it much lower

1) It's a Seidio brand, not some knock off, so it should be of good quality. It's been working fine up until the past month or so. I've had it for over 4 months now.
2) I've never drained the battery down to 0%. Contacted Seidio and they suggested that I let it drain to 0% for the next 4 to 5 charges, along with charging it an additional 2-3 hours after a complete charge. I'll see if that helps.
3) I've always had to bump charge it. It helps in making it last longer.
I don't think bump charging is helping the longevity of your battery. Not saying it doesn't last longer on a charge, but that it isn't good for the battery's overall lifespan.

Draining all the way down and overcharging it are the biggest ways to kill it off. The Seideo and most other batteries I think have a fail-safe for draining it all the way down, cutting it off early before it actually does.
This article is pretty helpful about your battery, if you haven't had the chance to read it, it may benefit you:

Bump charging did it.....
Where's ma rosie at?
I have been using the 3500 for about the same length of time you have been. I haven't really noticed a drop off in performance. Maybe a very slight drop off.. not much though. Still could get 2-3 days use on one charge if I wanted to.
I have the same issue with my 3500. I will try to re-calibrate it.
4 months seems to be pretty quick for a decline in performance like that. I would press Seideo to replace it.
You can try resetting the cells to how they were when it was brand new. All you have to do is completely deplete the battery of all charge (so it wont even turn on) then short it out with 3x the voltage (a 9v battery should work, make sure to keep the polarity the same) and fully charge it again, then it will be like new!
My dad (who is an electrician) found a guide for this on ebay and bought it just for the hell of it to see if it worked. We tried it on a battery I had for an LG VX8300 I had at the time and it worked beautifully, I've been doing it ever since!
I have no idea how this works, all I know is that it just does.

When ever you get a new battery you must condition it, exactly as sedio said full charge it, then drain fully 5 times. It makes the battery last much longer

I got some 3,500mAh cheapies off ebay about 6 months ago and they are holding up just fine. I always run mine down to about 5% then fully charge. I bump charge them about once a month.
Well of course... After I'm pimping how great these batteries are, one quit working! My phone would just shut off with a light tap against something so I pulled the black sticker off of the battery, pulled it all apart, found the loose connection, bent the tab to make better contact, and put it all back together. All is good again.
I recently purchased this same battery read tons of good reviews not sure how i feel about the bump charging after reading the article that was within this thread but all in all it is a giant leap beyond the stock battery now if i could just find a case that would fit around it
To the OP. If youre running a kernel with SBC (Superior battery charging [trickle charging] w/e you wanna call it) they're known to reduce your battery life. also you may wanna charge the battery to 100% then wipe the battery stats on your phone.
I have the same battery and I've found that the phone has trouble reporting the percentage correctly. It tends to make jumps of about 5-10% instead of a steady decline. I switched to the original battery and it did not have this problem. I've also noticed that clearing battery stats several times helps (most of the time). As far as bump charging goes, it's perfectly fine to bump charge these batteries. The worst thing you can do to them is discharge them all the way.
Clearing the stats and cycling the battery through the phone a few times should fix that. It does that (big percentage jumps) when it's poorly calibrated.

I second this. I have the same battery and its been off a few times. Battery stats get weird sometimes. It's certainly a better battery than the cheap Chinese batteries HTC uses.
