Tilt Battery Drain During Phone Calls

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,

Mugen powerbattery 1800mah for legend full review

Hei,
Ever since i saw this thread, I was considering a better battery for my legend.
To begin with the stock battery (Standard HTC battery) that came with the phone.
1. It used to last me for 2 hrs 10mins of voice call
2. If GPS was on it takes about 25mins to fully drain from about 95%
3. between 80to40% whenever screen was switched on, phone used to heat up.
4. At times (lately) even when the phone was in stand by in my pocket, it used to heat up so badly, i had to refrain from keeping the phone in my pocket. It actually felt like a "hotpack" in my pocket.
Phone is just perfect except for the retarded battery that comes with it. Whats the use an awesome phone if it you cant go through a day of light to moderate usage without requiring a charge?
So i decided to try out the mugen power batter. I love my legend, so even though battery was a bit pricey about INR.2,153.00 (USD46.95) (after shipping). I ordered a mugen battery 1800mah from their official website on 8th Nov. They took about 14 days to ship it to India from Hongkong (3 days waiting as batteries were out of stock).
Received it a week back. and currently i am running the 4th recharge cycle.
Immediately installed the battery on receiving it. (Couldn't wait!!)
The battery came with instructions to fully charge the battery (even after its fully charged as indicated by the green LED on phone) for 10-12 hrs for each cycle and nearly drain the battery before charging it again. (I took it to 5% each time, charged for a minimum of 11 hrs)
The fit
I was dead scared seeing the comments in this thread. But the battery was a perfect fit, infact the same fit as the stock battery. It would directly slide out without any poking / fingering
Tip - There is a small red plastic stick in the battery compartment to assist in battery removal. I dont have to use it though
The following are the actual statistics i have written down after each cycle. (Help me post a screen shot pls)
Recharge cycle 1
1st charge for 12hrs continuoesly
Voice calls 29% - 45min 44 sec
wifi 30% - 7 hrs 22min
Display 27% - 2hrs 12min (full brightness for 1hr)
Mpas 8% - GPS -23min, data 10mb
cell standby 4% - 7hrs 22min
phone idle - 2% - 5hrs 12mins
Total 7hrs 22mins from 100% to 6%.
Dint record the 2nd cycle, but was difficult to drain the battery in the next 13 hrs, had to switch on GPS + music on for 30mins on speakers + torch app with about 80% brightness for 1 hr to drain it before 11pm the next day.
I wanted to charge battery for atleast 10 hrs before leaving for office
Recharge cycle 3 Unbelievable!!!
3rd charge for 11hrs
Voice calls 12% - 1 hr 15min 12 sec
wifi + bluetooth 44% - 37 hrs 12min (dint turnoff bluetooth/wifi) transferred about 153mb in this cycle
Display 17% - 3hrs 12min (played angry birds for 1hr!!)
Mpas 13% - GPS -14 hrs 12min, data 43mb
cell standby 9% - 7hrs 22min
phone idle - 5% - 5hrs 12mins
Total 37hrs 31mins from 100% to 4%.
As you could see there was a drastic increase in battery performance after the 3rd recharge.
------------
Note - I am using juice defender (free version) + the phone is on strictly GSM only mode. (Exhausted my monthly data quota on 3g )
Currently I am charging it for the 4th time. Will post the final results again.
Also as froyo users are posting better battery performance, expect even more longevity of the battery once i receive my OTA (damn ever eluding update)
Conclusion - Definitely its a drastic improvement from the stock battery and the best part is it resolves the only problem i had with my legend, heating of the phone for no reason!
Makes me wonder why legend doesn't come with such a battery on default purchase.
Thanks Mugen for such a great battery
Do drop your comments and suggestions below or any standard benchmarking tools that i can use ...

Review part 2
< Reserving for 4th, 5th and final cycle >

Heating up is unusual with legend under normal usage, are you sure it has to do with the stock battery?
Some people did report problems with juice defender, your case may be different though.
Gotta say mugen battery was very lasting initially if you follow their instructions properly, but after using it for couple of months I don't think iam getting that same performance, its much less.. though still better than the stock one.
My mugen fits lil tighter than the stock one, its hard to get it out without that red lever. Iam kinda surprised about yours being the same fit as stock one. Dunno if they changed anything.

No heating issues at all after replacing the stock battery with the Mugen one. Havent changed / installed any new apps / software for the past 2 weeks. 1 week with the new battery.
So i can confidently say the stock battery is the culprit.

I've experienced the same short life when charging through USB, but when I use the wall charger, it lasts much longer.

Going to bite the bullet & try out one of these, just awaiting the money to be put in my PayPal account.

3500 extended battery decline in performance

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
Sources: I built one for my robotics team
Sent from my ADR6300 using XDA App

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.

[Q] I879 battery life

I have flashed my Att I897 with RemICS JB rom, and then I ran the battery dead. Then I fully charged it and it doesn't last 5 hrs now. I even calibrated the battery. Any ideas, or is this normal with custon rom?

Have you tried any other roms? Download a battery stat app let it run a few days and see what's using up all of the battery. Did this happen prior to flashing or no?

I have been running this rom for a few weeks, with no issues. Then went out and bought a new phone, and my brother needed one so I gave my I897 to him . I reflashed it, to clean everything up and let him put on the apps he wanted. And the battery does with in 4-6 hrs. I will d/l the stat app and see where is goes.
I have another I897 runnig the same rom, on my daughters phone, and it has great battery life still.

added thoughts
if your brother is making heavy use of the phone, with screen on much of the time, then 4 to 6 hours is normal.
running the batt dead once shouldn't kill it. there are protections in pm chip to stop before batt voltage gets too low.
aging, as in several hundreds of charge cycles, will reduce batt capacity to half or less of original capacity.
---------- Post added at 05:26 AM ---------- Previous post was at 05:17 AM ----------
oh, and swapping the batteries between the two phones and running a few days will tell if battery age is the problem.

I'd say it's time for a new battery. 2y old battery has significantly reduced capacity. I'm using original Samsung Epic 4G Touch SPH-D710 1800mAh battery, fits well in Captivate with stock cover. Battery life is very good for a smart phone. Stand-by >48h easily, holds >18h with about 2h talk + 3-4h screen on. Currently on SlimBean 2.5 ROM. Search eBay, it's about $15 only. Avoid cheap noname 1800mAh (or even more "on paper") Chinese batteries, usually the real capacity is well below claimed capacity.

I was getting a good 10 hrs on it till I reflashed it this last time. I had great battery life with that little phone. That includes texting and FB'ing talking
I have 2 more and I still get great battery life.

I've never tried RemICS JB but I'm in doubt the ROM itself is causing battery drain. I'm getting almost same battery live with CM10 Stable, PAC-ROM, SaltyBean SE, SlimBean. Currently running SlimBean. Make sure it's not an app you install after flashing the ROM. Never restore system data from your previous ROM, just user apps + data. Look at the battery panel and you'll see what is draining your battery. Btw, clearing battery stats does nothing. You can't really calibrate the battery. Android OS will adjust battery meter automatically after 2-3 recharges.

Yeah. I found out one prob was he was trying to charge it with just hooking it up to a pc. Know it seems back to normal since he used the wall charger, for a overnight charge

I've charged from the PC many times with decent battery life results... Don't know if that's the reason why the battery life has been cut short.
A good way to gauge what is causing the battery drain would be to do as ValD said. See what is using up the most battery life from the battery panel and try to deduce it from there.
Have you tried full wipe, re-d/l the ROM, and flashing the ROM again? Double check the md5 or sha1 code from the website when you d/l the ROM too.

yeah, some PC only provide max 100ma per port, which means ~ 15 hrs. and the cap in phone for usb is set to 350ma, or about 5 hours, unless you have kernel that supports fast usb charging.
still, if the phone was charged to 100%, it shouldn't matter whether AC charger or PC used. Was he not charging it to 100% ?
fyi, the difference to phone is that pins 2 and 3 of usb are shorted in AC charger. This causes phone to allow higher charging current, up to 900ma, or as much as battery can take without overheating.

Is the quick charge harmful?

Hi, I'm using my samsung phone with quick charger, however, I saw some people discuss that quick charge is harmful to the phone, is that true? anyone can confirm about this?

I can't say that quick charge is harmful however what is usually not a great thing to do is to stick the phone on the charger all the time when there's plenty of power left. Like charging it from 80% to 100% is just wearing on the battery life faster and causing it to use an extra cycle.. Think of it like this say the phones battery can ONLY be charged a total of 100 times and that's IT no more it's dead after the 100 charge.. if you stick it on the charger at 95% and charge to 100% well now you just lost a cycle and you only have 99 charges left.. Wouldn't it have been better to use the entire battery power until it shuts off and then charge it?! Doing it this way actually extends the batteries life and keeps it working a lot better than constantly doing small charges.

Ive always been taught that the faster u charge a battery the less charge it holds. And decreases the life span faster. That slower is always better on lifespan.
The added heat from quik charge also puts strain on device if being used at same time.
Just my opinion

Ive googled this and according to some psyhics, it doesnt matter how fast the electrons get to 3,000 mah. What really harms the battery is getting above 90% and below 10%. Everytime you get to 100% it counts as an cycle, and batterys have a limited life cycle. My orignal barttery went bad after 11 months...degraded from 3000 mah to 2,200. I manually replaced the battery myself

this is also true
i just personally dont think its good on them to quickly dump voltage to them either

Not sure it will harmful to the battery life span, but sometimes I charge my phone to 100% and continue, so this will also harmful to battery?

You can just not use your phone battery at all. Once lithuim ion batterys reach 100 thats it, they then drain from your electricty So by turning on your power case when uts at 100%, the phone drains from the case. Of course if your using like an 1amp charger, theb battery will drain if using while plugged in., because the screen is eating more energy than the 1 amp can provide

Batteries are cheap....replacing them isn't that difficult. I got 20 months from my original battery(always fast charged).
If I get the same from the replacement then it's all good.
Use the phone....that's why you bought it.

Yes, forcing a lithium battery above it's operating voltage, something like 4.7v with a 5v to over come is ok. But 9v!?!? That's degraded it's performance. In the great scheme of things does it really matter? Probably not, chances are you will get a new phone in a year or so anyways and thats about when the battery fails.

Oops

I don't want to change the battery, and for now, more and more phone come with battery non-removable, it's not a good choose to change battery.

Yes but how often? Every two years maybe?

I have never changed my battery since I owned my samsung s5 two years ago.
So how often will you change you battery? it is because the battery unavailable?

It's difficult? Could i ask you which battery to buy and where you bought it?

Its only hard if u want to keep your glass back. I tore up and shattered mine and dont care because my phone is always in a case, so youll never see the back. Got the oem battery from ebay for around 10 dollars. Then its just a matter of taking out all the screws, connecting the really small connector, and screwing back tightly. Like you need put pressure on screen when putting back together because for example volume down button might not work if press 2 lightly

It's easy, use a heat gun and the simple tools. Took me 20 mins and I didn't break anything. Just bought the battery off eBay
