Has anyone tried an extended battery yet? - Touch Pro CDMA

Although NSFAN's ROM has extended my standby time to almost 3 days, I wanted to try and push for more "active" time when using the data a lot.
I know there are two different battery types, one with more cells crammed into the same size battery and another with an extended door. Has anyone tried either of these and what difference does it make?

Id like to know too
Id like to know to what extent these batteries will allow my phone to run. I am running on Vets beta 3 and it sucks life right out of my battery (not complaining because it is an awesome rom) but I have also considered getting an extended battery since I also try running XDAndroid which eats the battery for breakfast...

I have both a Seidio Extra Cell battery (normal size but 1800 mah) and a 3000 mah extended battery with extended door.
Let me start by saying I own about a dozen accessories made by Seidio for the Touch Pro and Touch Pro 2....and they are all great..... BUT I only see a 2-3 hour stand-by difference.
With the 3000 mah extended battery (which you should be able to find for ~$20 or so) adds a little more... about 5-6 hours...... BUT it gets really hot, and the battery % drops like a rock after about 60%.
The combination I suggest is getting the Seidio extra cell battery and use it with a battery saving program/reg. settings. Here is one I install after every new flash. (as far as I know it works with all WM Roms)
Hope this helps.

so... do you think that they are even worth it? I had the extended battery when I had the Apache (ppc6700) but since it was bought used, I thought that the batteries were loosing charge due to the previous use...
I would like to get one but if they do not show significant gains, there is no need for the money waste.

Everyone with Battery Life Complaints...

For everyone with Batterylife complaints here are 3 options for you. NEW Updated Post.
Battery Adaptor Pro:
http://www.boxwave.com/products/batteryadapter/index.htm
This is by far the best option in my opinion for battery life problems. This little device about the size of the hermes, a little wider and very sleek / feels good in your hands. Its only $22.50 and worth every penny! What the device does is take AA batteries (4) and recharge your device via the USB cable. You can use the phone while its recharging too! What makes this device even more great is that is uses batteries, not its own rechargable battery, so on a long flights or long road trips or whatever the case may be, all you have to do is stock up on AA's and your good to go! It also comes with a flash light, VERY BRIGHT LED's for dark situations, although random, it comes in handy alot in dark situations trying to find your way to something or trying to hook the USB cable in. It recharges the Hermes about 6 times in my personal expirience with Duracell batteries. But get this! The best thing that makes this device worth every penny is that its compatible with ANYTHING that supports USB charging. This includes all other phones, Ipods, Personal video players, MP3 Players, Cameras you name it! Its great for keeping all your devices with battery power on any trip you go on especially if you travel alot. I no longer have to worry about battery life anymore with this thing. Its very small and easily can go in a pocket or a pouch in your backpack. No longer do you have to suffer with BIG bulky batteries to keep you going through the day/days. I highly recommend this unit and give it a 10/10!
You can Get an Extended battery 3000MAH from:
http://www.lionbattery.com/description.php?noproduit=477
Although very bulky the battery life boost is amazing. My friend has this phone (I don't have one yet, i just sold my 8125) and I have indeed tested it for myself. The battery will last you 10 hours before it hits 80% battery life. With these ten hours I was able to web browse, text message, use agile messanger, playing Doom 3D, Warcraft II, Sim City, Play music at 45% volume. at 60% batterylife I it had been over 25 hours already. With you constantly using 3G, push email and such Id probably say you can get a minimum of 35 hours of battery life with this battery. If you are not so hardcore You probably will get over 50 hours of battery life with this battery. The only cons I have to this battery are the size. its a great investment if you are one of those people always going on bussiness trips and such. You can charge both your stock battery and This battery and use the stock until it runs out then pull out the heavy duty. I highly recommend this battery. This battery comes with a cover for the 8525 too. 9/10
For all those who can't stand the size of this battery there is hope for you.
http://www.seidioonline.com/index.as...ROD&ProdID=333
The stock battery for the 8525 is 1350 mAh, and this one is 1500 mAh, this battery won't improve your battery situations much at all but it is cheaper than the option of buying one from HTC or cingular. You can get both the stock battery and this one and have them both charged to last you however long you need. Although a tight fit it still fits in the battery comparment and works with the 8525. 8/10
I hope this helps some of your frustrations with battery life with this phone.
-SonicCrackers
Pity about the thickness, but the sheer capacity makes one think twice... More than double the normal mah...
I just ordered the 3000mAh battery from lion's website - I'm getting low battery warnings towards the end of the day. I'll let you know how it works out!
lemme know how it is
Well, it's supposed to arrive today - I can't wait! My phone died before I made it home yesterday - very irritating!
Has anyone tried one of those 1500mh batteries? I don;'t want the extended one because my brodit mount will become useless and and just suxs. Anyone have an opinion?
http://www.ipods99.com/ProductDetails.asp?ProductCode=HTCHERMSL&click=35
Yey!
Well, I got my Lion 300mAh battery and I have to say I'm pleased overall! I'm still breaking it in but so far it has lasted a complete day with Wi-Fi on and a hour worth of movie watching. It came very nicely packaged from the company - it also has a 6 month warranty according to the paperwork. The battery is approx. twice as big as the OEM battery. My biggest complaint is the battery door doesn't fit quite as snug as the original... near the camera it has a chamfered edge instead of the rounded edge on the OEM door. Also, there is slightly more clearance to the left and right than the other door. After a week when the battery is broke in, I'll give a proper update on battery life (Lion recommends 5 complete charge/discharge cycles for maximum capacity). I have several pictures of it, but I can't figure out how to post them here ><
Im very glad the battery worked out for you lacroixdp . Yeah the non HTC made battery covers wont fit on the battery as much as it should but enough to get the job done. I'm glad the battery last as long as it does expecially with all that Wifi usage.
4 u slimsaturn the 1500 battery, there is no difference to be seen, its just a cheaper alternative to having 2 batteries to switch between on those long bussiness trips, for improving battery life however, u will not see a difference.
There was some talk of a 2000mAh battery for the hermes that wsa the size of the original one. I think it was supposed to be from lion battery as well. Anyone have any news on this?
Well after a few days following their recommendation on the complete charge/discharge cycle, I can safely say it is an excellent battery! At the end of work, I'm at 80% charge still. With the same usage before, it was always between 30 and 20 giving me low battery warnings. I DEFINITELY recommend the 3000!
I got one off ebay 3400MAH I hope its better or good.
I thought about that one but decided to stick with lionbattery.com and Mugen since they have a solid reputation for batteries. Plus I have a 6 month warranty to use if I ever need to.

I've had the 1500 battery for about a week. I cannot tell any difference between this one and the stock batter but for the fact that I have to use scotch tape to keep the back on. I used the Lion battery on my i730, but hated the size. I am ready to deal with the size due to the fact that I cannot deal with the shortness of battery life.

I Second the good rating of the 3000mAh Mugen Power Battery.
I bought it for my HTC TyTN from the Netherlands and alhough it bulges to double the size of the standard battery from the back plate - I like it though; gives me better grip on the slippery phone! - it gives me looong life compared to the standard issue (1350 mAh).
As noted earlier, along the sides the extended back plate does not fit 100% snugly, with a (very) minute gap on both sides. But not enough for the back plate to come loose though. Plus the edges (the rubber stopper at back - the antennae socket) is not smoothly cambered. Nothing a nail file couldn't fix though.
Great battery Mugen Power!
Haha that's even better I emailed in about the door and 15 minutes later I got a reply and a tracking number for a new door - excellent service! You've definitely earned a repeat customer! Are you coming out with an extended battery for the Treo 750 soon?

Hi,
I have about 3 months with my TyTN and I can see that battery life has been reduced. Battery duration is decreased and charge time I guess that is reduced too. Is there a known battery calibration problem or this is a normal behaviour for a 3 months old battery???
Regards,
Taguapire.
Because I am on holiday I had a chance to do a controlled test of the battery. I charged the standard battery, turned on the phone and made one call a day to just make sure its still working. I also forced the band into gsm only. My battery lasted 7 days from full to flat. I then did the same thing being only in umts and I got 3 days only. The test is controlled because I did not physically move the device at all in that time, so signal strength and tower searching would be kept constant.
I think that is pretty clear the 3g is the killer. The dopod 838 pro lasted longer than my magician would have under the same sircumstances.

Battery HTC StarTrek

For those at whom quickly to sit down the standard battery
http://www.lionbattery.com/description.php?noproduit=482
Here such battery 1900mAh for HTC Startrek will allow to work longer!
Wow. Does anyone have it? It sounds too good to be true for me. (I had some extra-capacity batteries from China or so and they were worse than original batteries. They were not for Qtek but for different device...)
Mugen batteries are generally reliable.
Sorry, clicked twice on slow connection.
Well... Finaly I have bought this 1900 mAh battery. I do not have it long but after one busy day I can say that this battery is really good one.
If I use the original 750 mAh battery, it would already has no power. But the new one is still above 50%. Well, I have traveled some hours by trains, read many news in rss reader, watch news in WMP, browse web (about 1-2 hours ), every 15 minutes checking for new emails, some IM... And the battery is still on. 56 %
The only disadvantage is the thickness. It adds 6 mm (0.236 inch) extra to Qtek.
Hey moneytoo, care to share some more expreriences? Is battery life much better, still after a month of use?
Thanks.
In week days when I use much internet connection the battery is enough for whole 2 days (no night turning off). Or the battery last for the whole weekend plus one week day = 3 whole days. Well - busy day = -50% battery life, normal use = -25% of battery life a day (= 24 hours).
So I believe it could run whole week (nights turned off) if there would not be much use. But I cannot test it because I really need to use my phone
Thanks for the quick reply moneytoo.
So it seems to me batterylife is more or less the same as a standard 1100mAh battery like on a Tornado device according to your experience. Price is about the same as the official 1100mAh extended battery. During weekdays I'm a heavy user of my phone so it seems to me this big battery is the right choice.
Thanks again.
my s300 is every time only and have a lot calls -> ideal working phone!
i use the office extanted batterie from HTC. the cover is very good. the most china made extanted batterie covers, are realy bad designed. if you can buy a htc version ... buy it :->
So the 1900mAh makes the phone about 6mm thicker? How much for the 1100mAh battery?
The 1100 mAh battery adds only 3 mm extra. And the cover is in sriped-style, but the 1800 mAh is not, it is just cheap plastic cover, but fits.
Good and useful information
Thanks guys/gals for this piece of information. It is definitely useful for people who are always looking for a plug to charge their phone.
The question is style(looks), versus practical(working phone)
Yes yes... thanks indeed. Very useful information.

How's the new battery life?

I currently have the 6800 with an extended battery. Previously I have the 6700 with an extended battery. Before that I had the 6600 with the extended battery.
With my current phone (6800) and the previous one (6700) with the original battery I can get to lunch time before my battery is finished. I get about 150 to 200 emails a day and have about 20 to 30 phone calls a day.
Will the new Touch Pro battery offer any better battery life or am I cursed to have a bloated phone with a big battery for the rest of my days?
Thanks.
You're likely to have the same issues with the TP. And since there are no extended batteries for the CDMA version yet, you'd be hurtin'. Great phone compared to my 6700, but battery life is not it's strong suit.
I have to agree. The battery life is abysmal. I thought about just buying a second battery, but decided to wait for an extended one instead...
Battery life isn't that great on the TP. I am a moderately heavy user with multiple e-mail accounts and about 50 texts a day. I can go a full day with the current TP I have. I had two other early models that, for whatever reason, the battery life sucked bad on. Considering what's under the hood we really can't complain too much about this. Its a great phone with loads of power.
I will never be able to do an after-market battery unless its the same size. No way I could rape this sexy phone with a big battery sticking out the back of the thing.
Not the heaviest push email or bluetooth user, but I do a lot of browsing and texting. I think the battery life is acceptable, about half of that of my Titan. I could make to the end of two workdays on my titan and have to recharge nightly on the Raphael.
Roms and radios helped a lot!

3000mAh Battery and cover

Have just bought an Hero 3000mAh battery and larger cover for £14.99 uk (free postage too) for a test. Will report back as to performance since it has just arrived and am in process of charging.
Only downside so far is thicker cover is black, but that is puerly a cosmetic factor and doesn't bother me too much. Am hoping that this will give me better than a days charge with Android 2.1 ROMs.
Am not sure that I can post where I bought the battery from on the Forum as this could be considered spamming. Could someone clarify if I am able to give the link.
I have just purchased one as well after seeing this post, Will hopefully be ok.
Initial impressions of the battery seem to be positive (pun intended). Had a slight worry when battery indicator dropped a single bar within an hour, 20 hours later and indicator is still sat at one bar from full.
Am still on my first charge and expect the battery to reach it's full potential (another pun) after a couple of charges. So far am very pleased with value of this battery and the charge it holds.
Could you maybe post some pics on how thick your hero is with the new battery
does a 3000Ma battery can do a damage to the phone?
if it doesn't, why everyone dont buy it?
Bit difficult for me to take photos at the moment, my camera is mounted up for my work and takes ages to set back up. The battery cover adds about 6mm to the depth of the phone in an area equal to the size of the battery. I actually have big hands and find it more comfortable to hold than the standard cover.

3000mAh is the capacity of the battery it should run for longer, not the voltage supplied so no damage should occur. The problem comes with quality control on aftermarket batteries, they can be of lower capacity than a standard battery, despite claims of a higher capacity.
There have also been cases of aftermarket batteries overheating and expoding, it is rare but can happen. I bought the battery as an experiment to see if it lived up to the claims and am prepared to take the small risk of serious hazards with the battery. In the end it's down to paying for a name and strict quality control, Kellogs Cornflakes or Unbranded Breakfast Crunchies.
The large capacity battery's make your phone fat and ugly
I rather work with 20 hours of total battery life with a beautiful piece of kit, then to run 40 hours with an ugly 80's looking fatso.

One thing I have noticed about charging this battery, is that the indicator will show battery as fully charged. I found that giving an extra hour after fully charged is shown will give a much better charge. So far the battery will give a good 36Hrs with Wifi continually on, haven't tried it with WiFi off for a long period, so far about 12hrs and it is still showing fully charged.
Thanks 13...
this was really helpful... i will go ahead and buy one
Has this battery worked good for you guys? No problems? I kind of need a bigger battery for the times I'm doing jobtravels etc. Earlier experiences in non original batteries are both good and bad. Bought a battery for my HTC Diamond, and the phone got fried. Don't wanna experience that again (even though my job buys me new phones when I need one)...
Just wanted to know you my experiences.
I have a 2600 mAh extended battery and my running time of the phone with enabled WiFi and Nimbuzz is about 48 hours. Without WiFi, pure Standby, is about 85-90 hours.
You need at least 10-15 recharge cycles to get the full capacity out from the battery.

Sounds great. I might have to try one of these batteries. What battery did you buy?
I bought one of this too, off Ebay. Although the phone is a bit uglier and slightly heavier, the battery seems to last between 2 and 3 times as long. I gotta say it's totally been worth it. The extra size isn't that noticable either...most people look at the front, right?
Well i bought one and i rly dont like it.
Its almost a half centimeter bigger and allot heavier.
So be ware the phone does get ugly but you do get more battery power.
Tbh i rather recharge my phone everyday then make it so ugly
I've just ordered this battery.
Can any one give some real numbers? For example how long will it last with 3g network active. I bought this one for outdoor activities when I can't recharge for a few days and I would like to know how many days I can depend on it.
Thanks!
I rooted my phone and tweaked the crap out of it.
Runs 48 hours with standard battery now.
No need for fat and ugly
I have this battery + cover too.
Because it's bigger, I find it easier to press the hardware buttons on the bottom of the front of the Hero. THe only drawback is the total volume in your pocket, but that's just a minor point.
Also, flashing Modaco's 3.1 Rom and the newest RADIO Rom, the phone lasts for about 6-7 days with normal use (wifi/3g on when i need it, some regular phonecalls/texts)

[Test]Laza Z-cell 3240 extended battery

okay so i just received my 3240 ext. battery...i will do several tests once fully depleted and properly recharged...the battery was slightly below full charge upon installing...Im trying to make these tests as scientifically accurate as possible (variable free and unbiased). once i get this first cycle done.
i will test according to the following:
*i will not test with any variables (this includes signal strength), so while running these the phone will be in airplane mode
*also to ensure consistency i will wipe the phone completely and freeze any apps that arent critical to the function of the phone
(although im tempted to install neo adrenaline 2.0 for these tests, if only to eliminate any bloatware from skewing results)
*aside from unlocking and superuser (needed to calibrate the battery after first full charge), unless otherwise stated, the phone will be completely stock (605.12)
(unless i do install adrenaline 2.0) either way the tests will be coducted in the same manner each time including rom and apps installed
*in accordance with the least amount of variables rule i will keep the phone at full brightness, screen on, while running a stress testing app (this will help shorten times between tests as im trying to kill the battery as quickly as possible
*these series of tests will take quite a while to do
(hopefully, if all goes well and if this battery is up to its snuff, itll be a ***** to drain)
*results will be published at the bottom of each full discharge cycle (phone turns its self off), and will continue to post results until the 10th discharge
*on the 11th recharge i will enable the antennae and rerun the test to see how much the signal strenght and such affected the actual life of the battery
Any suggestions on what else to test for or if im missing anything?!?!
i know setcpu has a stress test built in but id like something to stress test the gpu and cpu at the same time if at all possible, any suggestions are welcome.
which apps would you like to see used in the test, since i know setcpu isnt the best option for this...ive heard battery monitor widget stated a few times in other threads since temperature is also a key factor, i will consider it.
comments, concerns?!?!
if this turns out well i will run these tests on other batteries...
theres no way im going to pay for a mugen power battery...so i propose a wager...ill gladly pay for one if it does out perform every other battery i get my hands on AND if the power rating is with in an acceptable range of their official rating (4000mah) upon completion of testing...
ill contact mugen power and set up the challenge
There's an app called Stability Test in the Play Store that has a CPU/GPU stress test mode, and it supports multi-threading, so it should work for what you're wanting to do.
awesome...i will look into it
how did the testing go?
I just got my laza cell 3240mah battery myself, only gone through 2 cycles so far. I've also got the following batteries if you'd be interested in testing any of them.
Stock HTC 1620 mah
Extended HTC 2750 mah
2 Ebay 3500 mah
2 Ebay 1800 mah
this battery is great.
i have had some problems with the phone rebooting, but that could be my phone, not the battery, and it doesn't do it all the time.
the phone easily lasts all day and usually most of the next day when i forget to charge it at night, and i am on my phone extensively.
I have been looking at the laza also. Great price on Amazon.

Laza extended battery
I bought an extended Laza battery on Amazon an I've been using it for a couple of days now. I'm only on my 3rd charge cycle but I can see a major improvement in battery life. For $30 (including shipping), it seemed to be a good deal.
What I don't like about it is the back cover that comes with the package. The antenna material inside the cover is pasted with some really gooey adhesive and it's a lot thicker than the OEM stuff. That makes the closing of the cover difficult, as you have to squeeze the antenna between the phone and the cover itself. Also, I noticed that one of the tabs for holding the cover attached to the phone was missing on the volume rocker side. That causes creaking and leaves a gap between the phone and the cover on that side. There is also a gap at the top, that never closes, as the retaining tabs are in the wrong position. I wrote to Laza and they said they'll ship a new (and tested) cover to me next week. I'll report more when it arrives.
Is the battery percentage accurate with extended batteries?
Sent from my ViperRezound via Tapatalk
I received the second cover from Laza and it seems to fit just as poorly as the first one. Also, it was supposed to be tested for the 4g reception, but it drops my 4g twice as often as the initial one. The battery is holding its ground and charges to 3248 mA overnight. With 4g enabled and moderate to heavy use of the phone, it lasts 6-7 hours max, with juice saving tweaks and the screen at 30%. I haven't made up my mind if I want to return everything and get the OEM battery and cover, or just keep this stuff and deal with it's shortcomings. Obviously, I can't recommend it to anyone due to the poor quality of the back-cover.
Sent from my ADR6425LVW using xda app-developers app
If this battery lasts longer than the Verizon extended battery, I'd be interested in just the battery without the cover as I use the standard cover cut to allow the extended battery to stick out, and then a modified defender case.
I think he could sell the battery alone for half the price, but does not do so at this time.
I use this battery with the OEM extended back cover. After extensively running data speed tests(nothing official just a million runs using the speedtest app with each cover) I was able to determine that the LAZA battery does in fact run cooler, as the Amazon reviews state, than the OEM batteries. It also gets longer battery life than the OEM extended battery, however i have no numbers for this just regular usage/charging times i had. But between the 2 LAZA back covers, i never seemed to be able to snag quite the dl speed i got with the OEM covers, however my upload speed on the LAZA covers strangely doubled what the OEM covers got. Who cares about the upload speed though obviously dl is more useful! So in general LAZA battery with OEM extended cover gave me the best results for heat, battery run time, and data speed. Reception between all the covers(OEM extended, 2 LAZA extended, OEM regular cover) was virtually the same. I hope this info helps someone because i know when i was looking for this exact same comparison i could find nothing except for the shady Amazon reviews.
im getting well over two days of light usage (mostly idling), and around 15 moderate (web browsing, videos and a few hours music) about 7-8 hardcore gaming (nova and gta3 w/ preset draw distance and resolution)...this battery is a must buy except the backs rubber texture has begun to peel a little...signal strength is great and runs extremely cool...only times ive had issues with the battery getting hot or draining is when its encountered a renegade app that refuses to close or idle, which is hardly a battery issue
Do I need a separate cover?

I have an HTC OEM extended battery. I can fit a spare battery in my pocket but don't feel like carrying an extra cover. Will this battery work with the HTC extended battery cover?
yeah...i believe its exact same dimensions...at least from the other reviews ive read they are interchangable with is cool cuz the rubberization on the laza case is peeling off...it does look better than the oem extended cover at first but yeah it should fit fine
there is no drop in the 4g
i have had this battery for a couple of days and i can honestly say that my 4g reception has been better! Laza updated their product because they saw all of the complaints that's why it says "extended battery 4g" when you get it
