Hi guys,
I've noticed recently that my battery life is getting shorter every charge. I don't know if I'm running too many apps, or my use is too constant.
In the last week or so, I've noticed the battery gets really hot while charging via AC adapter (40 C according to my battery indicator app), but not so much when charging via USB. Has anyone else experienced this? If so, have you fixed the problem?
Also, what can be done about replacing a faulty battery, as It's built into the device?
3 month old 3G/WiFi Flyer, running stock Gingerbread ROM
I'm using Dr Battery Saver. When tablet comes to 15% I connect the charger (not USB) and charge it at steady state. So far it's going ok. The 3G and WiFi status could affect the battery performance.

This was happening to me. All I did was just turn on Airplane mode when theres no wifi around. The battery became great after that.
The battery is not replaceable (easily). It's normal for it to produce more heat when charging from the fast charger vs. USB (very slow charging).
Check your battery stats. in settings to see what applications are using the battery the most.
The battery is becoming a threshold for new gen smart devices, especially tablets that consume a lot of energy with bigger screens. The producers also have to focus to develop new gen batteries with higher capacities along with "environmentally friendly" features. Imagine a Flyer with a battery lasting a week with full funtions?
Thanks guys. Will try all suggestions.
I think its stupid one can't replace the battery. Yes the Flyer's construction is more solid than most, but what happens 2 years down the line when the battery does not perform as well? Even hybrids & electric cars have limited battery life, & those are supposedly the most advanced in battery technology. HTC should look into this with future tablets...
I can't think of a single tablet that has a replaceable battery. The assumption is that in 2 to 3 years the hardware is so outdated, no one would care.

Have you run through the lists of programs running from startup and also turned off the syncing of accounts you don't need background synced?
I've put most onto sync when opened only, and easily get 2 days including using Notes as my only form of paper for work...I.e. 2 to 3 hours of writing.
Also check you are on the latest f/w or even do a hard reset. Too many installs!

proper cycling might help revive your battery
Give it a couple of decent cycles.
1. run the battery completely down until the device shuts down.
2. let it cool for an hour.
3. keep it powered off, plug it in and give it a full charge.
repeat a couple of times. Heat is one of the worst conditions for affecting batteries over the long term so #2 is pretty critical. I usually do this every couple of months with my gadgets. Bonus with the Flyer is the giant aluminum heat sink!
and practice good app/connectivity habits. ie. set it to shut down 3g whenever WiFi is available etc. and don't keep anything running you don't need immediate access to.

I was wondering when someone would recommend getting a new oem battery for the eris? I've had mine for almost 2 years now and it seems like my phone dies quite quickly. Of course my usage varies (usually depending on if the girlfriend is working lol) so i can't be sure. Furthermore its not like i kept logs of my battery life when i first got the phone so its not like i can accurately compare to my past life. What do you guys and girls think? The oem batteries on ebay for like 5$ are quite tempting at this point.

I was noticing definitively lower battery life in May this year - so, when my battery was about 16 months old - and bought a new one, and battery life definitely improved back to my old normal. I had to weight that against the realization that I was planning to upgrade my phone sometime around mid-August to late-September - but it was still worth it to me. It's a lot less of a hassle than making sure that I am charging a couple of times a day.
I think that, given the charge cycles that phone batteries typically get, this is pretty much expected.
Do it.
Also, there was a thread around here somewhere (in the Droid Eris Q&A section) about OEM batteries for about 10 bucks. I'd say that's a pretty good deal.
Alright thanks, i jumped on it, should be here by monday. Ill let you all know how it goes

You should be fine with it - especially for under $10 - I ordered a HTC Ozone OEM 1500 maH battery for the Eris (which I knew would fit tightly with the stock cover) and nearly 6 months later, no issues whatsoever & holding charges. Recently ordered a LG ENV3 (OEM) battery from the same NY-based eBay merchant and it put new life into DW's 2 years old "feature" phone.
I kept the "old" battery charged & keep it alongside with the headphone & usb cable handy when I'm on the go for contingency purposes, occassionally rotating between the 2 batteries.
I've had my Droid Eris for almost 2 years and noticed the battery life was becoming horrible. To the point of having to keep the phone plugged in all the time. I purchased a brand new oem battery and STILL have the same issue. Now its worse those, it will suddenly die and when I restart the phone, there is NO charge. Any suggestions?
Did you try calibrating it?

I had my battery die on a hiking trip (I was using the camera a lot) and bought a spare battery when I got home.
Not long after that I rooted my phone and put Setcpu on it to lower the clock speed when the screen is off. I now get about double the battery life. I have yet to need my spare battery, but I swap back and forth every few weeks.
my first reply
I'm try to post my first reply in xda...What's going , I'm looking forward to this message...
Are you using a battery monitor on the Eris? I highly recommend using it as you can check to see what's running in the background (i.e Maps did manage to stay on or come back - maybe, delicate touchscreen issues ??) that might be "draining" the battery - even after a proper calibration & several full charge/discharge cycles.
Depending on the custom ROM, it could be the widgets, clock/weather/news app, email, or even screen settings, etc. Up until last week, I had a nearly 30 months old HTC battery (from the Ozone @ 1500 maH) in the now decommissioned, WiFi only Eris and it was fine - holding a solid charge for typically 20+ to 30 hours of light/moderate usage & standby time.
Hi,
I'm just about to take the plunge on one of these. What kind of battery life are you getting, generally and also say watching films?
Also, does it charge via the usb?

Im getting around 7 hrs on mine most of the time, last night watched Dawn of the Dead on it from fully charged and was at around 85% when it was over so can probably squeeze in 4 movies or so. And sadly no doesnt charge via usb just from power connector/dock.
Battery life is comparable but lower then most other tablets.
I'd say it's on par with Xoom... maybe a little worse.
Mine has been on for 1 day, 10 hours, and 34 minutes so far since last charge... but this is with the unstable wifi policy.. I have it set to never switch off, however it just randomly connects and disconnects when the screen is locked.
Battery life is fine especially considering the smaller battery. I do wish they put a regular sized battery in there and gave it a few extra hours of juice. This device is also so light (well balanced) that I wouldnt have even cared about the extra weight.
So, I made a switch from HD2 running android to Amaze hoping it will have a better battery life coz of its juicy more 1730mAh battery, more power efficient s-lcd screen and the fact its an native android device (which the hd2 wasn't) but its been barely 2 days and I'm seriously disappointed with it.
I'm have a moderate usage which includes calls, pandora, youtube and net surfing but it barely lasts till evening and the usage is actually less than what i did on HD2 coz I don't have put any games on Amaze yet. I had lots on HD2. With HD2 I could easily pass through the day and still have about 10-20% battery left at night and this was on its anemic 1230mAh battery
I do realize the HD2 was rooted and was running CM7 and had all kinds of custom kernels and stuff. So is stock Sense and HTC kernel the culprit here ?
I've already ticked in the setting for Power efficiency under power settings which turns off auto sync (I have google and facebook sync same as I had on HD2) and using auto brightness with the least setting, but neither of them are helping
One thing I noticed in current widget log and current widget display, is the power drain in standby hardly goes below 100mA anytime ? According to me, this seems to be the issue hogging the battery as on HD2 it used to be <10mA most of the times with occasional spikes...but in Amaze every value is like more than 100mA. Does the faux kernel and custom ROMS helps with this, a lot ?
Ideally I should try it myself and see, but don't want to unlock the bootloader and stuff just yet as if the things are going to be like this, I may as well sell it and put in some more money and switch to other side (sgs2)
The other theory I have is the CPU on HD2 is single core 1GHZ while Amaze is dual core 1.5ghz. Gingerbread doesn't have proper dual core support so things will improve when ICS comes ?
Also on a side note, is there a problem with earphones having L shaped jack on Amaze ? My primary headphones monster turbine pro which have L shaped jack don't have a very good fit in it and small amount of force seems to disconnect the headset from phone. Its really annoying, although my other earphones which have a straight pin don't have this issue. But its not the earphone problem either as I don't have this issue with turbine's in my mp3 player and HD2 ?
The stock battery was horrific for me so I bought the Anker 1900mah battery from ebay and It's far better than stock...I'm at 15 hours with 47% left...Tasker is helping a lil also.

Hmmm didn't think i would have to upgrade the battery just after buying it, although seems something wrong is with the battery though...maybe HTC just bloated its spec to 1730
Yea, I have advanced task manager with auto-kill, but its really the same with it or without..

Try letting the battery discharge completely until phone turns off, and then plug it up and let it charge to 100% without unplugging it.
My stock battery last 12-16hrs depending on use. I also have an Anker 1900mAH last a good 18-20 if I charge it inside the phone. If I charge it with the Anker charger it last about 8hrs.
Guys what about the current widget numbers ? Have anyone of you got it or can get it to see how is the drain like for you guys?
No matter how strong the battery, if its going to [email protected], it won't last very long. 18-19 hrs on after market 1900mAh battery isn't very impressive figure either
I'm not quite sure of this drain, is the fast 4g on Amaze the culprit just like LTE
Also let me know if you guys have stock or custom ROM ?

You should use a battery saving app like juice defender or battery fu.
Personally, I use battery fu and I have gotten more than 20 hours of battery, on stock battery, running on stock phone, unrooted.

I havent had any battery life issues with mine. Before rooting I could go the whole day on a charge but it would be close to dead around 10PM. I'm still getting used to the new ROM I flashed but battery life has definitely improved.
I would recommend opening the task manager and killing off some unneeded apps.

Using task managers to kill an app that you don't want running isn't bad, I think its the continuely killing all apps every 30 minutes that makes it worse.

I'm not sure why this should be high
It should be low ? A high number would mean its losing more power during standby...
Guys, There are 2 school of thoughts about task manager...I agree task manager may consume more battery if you look into the theory how android works...but I've tried with and without task manager it doesn't make much of a difference from what I observed
Also what about L shaped jack earphone issue? Is it fine for everyone else?
I have the same issue my battery lasts 6-8 hours MAX with intermediate use....juice defender, tried every rom and different kernels.
My brother Easily gets 16-18 hours with intermediate use (galaxy s2) same processor. I know his battery is a little bigger but I didn't think his battery life would triple mine -__-

Hi Glacier,
Thanks for the update That seems reassuring...
I've been researching on Amaze battery quite a lot, I think current widget numbers are misleading because even in Airport mode it shows more than 100mAh drain, which is not possible..
I've found out another app...My battery drain analyzer written by a fellow member here at XDA
https://play.google.com/store/apps/details?id=com.WazaBe.android.BatteryDrain
It basically calculates the drain rate in %/hr, basically measures how much time does it take for battery to take 1% dip...
I've found for my amaze its close to 1.6-3%/Hr when in standby, when phone is not woken up during the period...I think its on a higher side but acceptable still...Can any member with a custom ROM/kernel also report his/her number..
BTW I've seen the numbers on TMO SGSII in their forum, this number is roughly the same there too ~ 2%/per hour for most users...
Did HTC change the way devices operate when plugged in?
With the original evo 4g, it would run off the battery even when plugged in. Is that still the case with their newer devices (including the lte)?

I don't know the answer, but a fascinating question. Laptops don't run off the battery when charging (at least I don't think any ones I've ever owned do). So why should phones? They're basically little computers now anyway. I suppose we'll need a manual to know the answer, or an HTC rep.
While I agree with your assertion above, that was not the case with the original evo.
As is recall, this is demonstrated by using battery monitor widget or similar, with history enabled. The data would indicate that once the phone reached 100% charge, it would begin to discharge until about 90%. At this point it would start charging up again (until 100%) and the cycle would repeat.
If the phone is running off the charger while plugged in, the battery level should remain at 100% the entire time. Sure there were kernels available that would change the charge rate or thresholds. Anyone with an evo 3d care to chime in?

That seems rather silly - what if you grab the phone off the charger when it is just down to that 90% marker? It will show up as 100% I presume, and then drop rapidly down to 90%? Hmmm... No wonder those SBC kernels are so useful!
It's the same reason most new laptops give you a battery health option that only charges to 80% if you keep a battery at full charge for an extended period of time the cells will overheat and eventually lose some of their charging ability kinda like when you use a float charge on a lawnmower battery it's on a constant charge and discharge to keep the battery healthy same rule applies here.
Whatever they do/did, I hope it's well thought out, considering the battery is not removable. Once the cells degrade,...phone is shot. A bit disappointing. I'm not here trying to fight about nonremovable battery and how long it will last, and ability yo swap out batteries. But the idea that battery degradation (which is inevitable) = shot phone DOES give me pause and concern.

Even after a year, there is noticeable diminished battery capacity. I've had the seidio 3500 in my original evo since about feb or march of last year. Fast forward to same time this year. I'd say it easily lost 20-25% capacity. With my typical usage, I could go for up to 4 days without having to recharge (yes, light user). Now, it's 2-2.5 days. I was bothered by it enough that I did an rma. Seidio said that's normal wear and tear. Fortunately, the credit card I used had an extended warranty feature too, so that's what covered it.
There will likely be a tear apart video/howto posted eventually on the evo lte. Although the battery may not be typical user replaceable, i'm confident it is possible to open the device with minimal damage.
I'm sure there will be a way to switch batteried, you'll just have to go to a phone tech probably. I'm not worried anyways, I'm still using my stock evo battery and it's still going strong

I'm sure you can fork over some cash and get the battery replaced. I wouldn't lose any sleep over this. iPhones have survived with non-removable batteries for many years (although I always used that as a "con" in my comparisons between Apple and Google's respective phones).
My Evo 3D will discharge to 95% then back to 100% and repeat. It is done to keep the battery in good health longer.

This is true, But iPhone users have no choice. So they get used to it.
Android, at least for now, has choices regarding removeable batteries.
IPhone users also have a 3 1/2"? size screen, which they got used to.
I'd Never purchase an Android device with that size screen, even if it was available. I highly doubt they'd sell many of them with that size screen.
Reminds me of when I thought my HTC Touch Diamond's screen was so large, compared to my previous clamshell devices prior to that lol!
It was such a nice screen for its time, just like the iPhone was a nice screen for its time, but that time has long passed, except for iPhone users :-(
Hi fellow l9'ers
I purchased an OEM battery to have as a spare battery since I'm usually out of battery when I most need it but forget to bring it or charge it. After having so-so experiences with aftermarket extended batteries on other phones I decided that if I wanted good results on the cheap I need to make it myself. Still testing it out but initial impressions are good.
BTW.. yes it looks horrendous and I do know that it could blow up, ruin my phone, cause cancer and start WW3.... but thanks for your concern.

9/4/13 Update.... after using it on a daily basis and swiping back and forth between the oem battery and my jerry-rigged battery I can say its definitely working. The performance has gotten constant and I did a battery drain comparison between the 2 using the app called FAST DISCHARGE. All option selected and cpu set to full load with temp set to unlimited. I did remove two of the jumpers and only left positive and negative connected.
OEM BATTERY........... 2hr 5min 13 sec
JERRY-RIGGED BATT..........3hr 35min 21sec
I suspect that it doesn't last double since both circuits are being powered when charged...... the first battery to be fully charged send a signal to the charger to shut off hence the lack of full power.
Over all for $10 bucks I'm not complaining.
How does the battery stay in place? double side tape?
Also, what is the battery life on this uhmmmm... phone?
How is it?
I am very interested in trying this if your results are good...How has your battery life been affected? Has it doubled? Do you use a case that works with the new "power bulge"?
I did that to my old i897 captivate. you only need the positive and negative connected. you're connecting the two circuit boards together which may cause problems. i would remove that one. Unless you can find a battery charger that supplies more amperage you most likely will never get that battery fully charged no matter what the android meter says.
Ok, after a few days of heavy usage I have come across sporadic performance results. In a few occasions it would out last the original battery under the same usage and other times it would perform as a stock battery. I plan on purchasing an external charger since I suspect that both batteries are not fully being charged as the previous post mentions. I will also disassemble the second battery and take the circuit out of the equation. So far I am pleased with it's performance even though it's not consistent.

Cool. i work in batteries so i didnt check out dudes guide other than his soldering was good lol. essentially all you're doing is connecting the batteries in parallel. since both batteries have a circuit board that controls low voltage and temperature safety, you only need to use one as the battery will still be a 3.6v cell just double the capacity. stock LG charger shipped w/ L9 outputs .85 amps so if you could find one that did 1.5amps or 1500mah you'd be in good shape.
Like @Meda808 said,you only need to connect two pins... + and -.You will also need stronger charger but... There is a circuit in a phone which controls power to battery(I think that that's why is one of the two middle contacts on battery) so... Maybe with external charger?

Small update......
So far so good, no major issues. I purchased the anker standalone charger and it charges the battery but it takes way to long(10-15hrs) So I just charge it in the phone now. The battery lasts me a full day under heavy heavy usage. Prior to this by 2-3pm it was out of juice.
I have noticed that it has become less sporadic the more I use it.
Iheartradio 4-6hrs a day, dish anywhere 2-3hrs a day, calls:30-1hr. This is with WiF(thanks Home Depot), data and Bluetooth(LG Tone)on for most of the day.../.. I'm happy I did it.
I unplug at 4:45am and plug it in by 8-9pm with about 20-30% left.
I have not modified the connection yet so I suspect that it still might not be fully charged even with the aftermarket charger.
About the hump..... I got use to it quiker than I thought.
