Hi everybody.
plz someone can help me to find a good battery in ebay for my kaiser?
I read about some batteries with high mA capacity but the same performance than the original battery, and some vendors and very bad quality batteries.
so I'm a little bit confused, I want a battery with better performance than the original, but with the same size (of preference) or not too big.
if someone can tell me about a good vendor and his best battery model I would be been thankful with him
PS: plz don't burn me by open this topic so vitiated.
Ps2: sorry about my english
I'm using this battery which is technically twice the capacity here:
http://www.superetrader.co.uk/htc-t...lacement-extended-battery-2700mah-p-3052.html
It comes with a new back casing because as you would expect it is literally twice the width of the original battery so it sticks out at the back. I haven't had any problem with the quality of the battery, but the casing does feel a little bit cheaper than the original.
This one comes with 12 months warranty, which you are unlikely to get on Ebay so bare that in mind when you do your purchase.

Technically, yes...but in normal use, does it actually work? Does the battery work longer?
ive used an incredibly similar style of battery for an older htc phone. I used a battery with twice the mah but didnt quite get twice the life. dont get me wrong, did the job at increasing the life pretty well and u get used to it sticking out a bit on the back
ps, if yer using a tight carry case then it may not fit in with an upgraded battery

that is exactly my question. in this case, which battery is better in weight/size/mAh/performance?
Im using the 1600 mah from www.seidio.com. Barely adds any weight compaired to OEM. Batt life for me is extended about 4-5 hrs. On OEM, with normal usage, I am down to 30% by 10pm (I charge overnight 12am-5am). With the 1600, I am about 45% at 10pm.
All my products from Seidio have been solid. I would stray away from batteries bought from ebay. I got lame ones several times when buying batts for other phones, cameras and devices.
I forgot to add that the 1600 does not need the extended back cover. It is the same dimensions of the OEM. Also the 1600's weight is, if anything less then the OEM. The metal bars/frame on the OEM battery is not there on the 1600. Some say that the metal bars are for reception. So far I have not noticed any reception decrease nor interference difference.

I live in Chile (southamerica) in the ass of the world.
the only easy-fast way to buy something is ebay
I am so lucky I guess, I never had a problem buying this way always looking the vendor feedback/reputation.
thanks by the advice
I think the best battery is that http://shop.eten.hu/mugen-power-300...5-cingular-with-battery-door-black-p-207.html

Why do you think that? Have you compared it to the other extended batteries (including the cheap ones on eBay)? As far as I can see, they're all pretty much the same.
As far as I understand, all the extended batteries have the problem where the Kaiser incorrectly reports the capacity and shuts off when they're half full.
Have you seen this post? http://forum.xda-developers.com/showpost.php?p=2097942&postcount=48
FWIW:
We have few older htc phones at home (ipaqs, tytn1, tytn2).
I bought extended batteries for ipaqs in the past - original from HP's store, and 2600mAh and 2400mAh "generics" from ebay.
Contrary to what I've been "warned" by some people, there was no problems whatsoever with any of the "generic" batteries - they didn't explode didn't damage my phones, nor didn't malfunction prematurely either.
The 2600mAh made in China lasted me 1yr 3mths before it started to act up, the 2400mAh Taiwan-make still works (its been 1yr 5mths now) - and both are no-brand cheap batteries from ebay, and the HP's expensive extended batt (IIRC it is mere 1800mAh only) still works too (almost 2yrs now).
The only problem I had with the extended batteries were their replacement back covers.
Except for HP's original one (of course) which came with 2 extra covers, the "generics" came with really shoddy and crappy covers, the China-make one was the worst: it was slightly out-of-specs, and it always felt somewhat loose (no, it never felt off nor unlatched itself but it had this "loose" feeling always, you could physically feel it moving a bit up and down when holding the phone, not much - maybe half a millimeter - but it was there).
The other Taiwan make battery's cover was perfect in its dimensions (no "loose" feeling) but then its color was few shades off of the original color... not really important detail (specially when you pay 3x less than for the "original") but I thought I should mention it too.
I have just ordered Mugen extended battery for my TyTN II.
When it arrives - and I won't forget - I'll post here about it.
****, I am really confused now
thanks justdave by the advise.
just get a ebay cheapo
http://cgi.ebay.com/EXTENDED-LIFE-B...ryZ20336QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
this is what I ordered. from this seller. battery cover fits perfectly. no wiggle. battery lasts all day without worry with heavy usage. talk, email push, web, im on it all day.
It does not report the battery meters correctly as with all extended batteries as noted. but this battery at 23 bucks shipped is the so much cheaper and I am betting the exact same cells as a seidio or muggen battery. they are all made in china anyways.
An alternative may be an external USB power pack. I use one of these and top up when my battery is going low. Saves the hassle of a larger phone, and all i need is a standard mini usb cable
http://www.proporta.com/F02/PPF02P05.php?t_id=2725&t_mode=des
I am also using the seidio extended life 1600ma battery, i used to charge my phone every night because id be down to like 20% after a day of use, now with the 1600 i go 2 days of use and charge it the 2nd night almost always. Also you retain the original battery cover. I dont know about you guys but this phone is dookie enough as is, i dont need a big battery that requires a new cover and makes my phone another 1/4 inch thicker. seidios a good buy imo, little pricey but ive been happy with its performance.
Extended Batteries
I have an Electrospan by Boxwave @ 2600mah and a Mugen 3000mah. Yes, I think the Mugen might be a little better, but what is interesting is the batteries are exactly the same size although the back covers are different. They do make the device thicker, but it still fits in most horizontal leather cases I have tried. Boxwave also sells an external battery pack that takes 4 AA batteries. The key is to minimize battery drain in the first place. If your data like connects to 3G, battery life goes away quickly vs. edge or GPRS. You can restrict this by using Bandswitch # www.commmgrpro.com (10 euros). Voice calls, screen brightness and push email can also contribute significantly to drain.
And here it is, the original battery with a new 1600mAh cell
Don't know if it's really 1600mAh, but it's definitely better than the original Sony cell

I got the 1600mAh cell for HK$32 (US$4.12)
From personal experiences though, DynaPack isn't that great. If you don't take proper care of it (like this guy I know of) the battery can really go bad.
Anyways, I just bought a MOMAX X-Level 1400 mAh. Lasts longer than the original and is of the same form factor.

It went bad already. I took it apart and replaced the crappy Sony cell inside with a brand new 1600mAh cell
I absolutely will never buy anything from Momax again. I bought a Momax BC60 battery for a Motorola phone, it says 900mAh on the packaging, but the cell is actually 400mAh(!) only Found this out after peeling the sticker off.
more mAH means the battery is heavier?
more maH means longer running time and longer charge time, but that doesn't translate directly into a heavier battery. If size constraints were inexistent, then probably the manufacturer would simply add more cells to the battery pack, but since there is a contraint, mah would depend on the cells' chemistry.
I am using a DynaTech 3.7v 1400mah battery to replace the Dynapack battery that came with the phone. It lasts for about two days in between charges on days when I seldom used the phone other than SMS, one and a half days when I use GPRS/GPS/WiFi. It gets pretty hot though when charging...
One very good choice is
the 1600mAh Cameron Sino I bought one from amazon.uk for I think 16euro.
This is my second one the others last more than one year of havy duty. A lot of GPS and WiFi almost every day. Good battery in my opinion.
i have the same battery since maybe a year. it was great, until 1 or 2 months ago, when the life was gone. the battery drains for 3-4 hours when i play music. the original battery is way better in durability.
my 3000maH battery
this battery lasts on average 5-6 days on standby time on WM6.1 full ROM
gps | wifi | BT | 3G OFF
it is pricey though $80 something
battery does not fit with regular phone cover so a new cover is provided by mugen which has a nice glossy finish and looks quite good on the phone.
2 BAD points
no opening on back cover for GPS antenna as there is no antenna in the market to fit the raised back cover.
no camera lens cover, just a cut hole in the plastic with a silver-colored plastic covering.
i protect my camera lens using a single layer of clear cellotape, pictures come out quite decent.

Hi all,
Bought my 6P used a year ago to the day.
Recently, along with the ever-looming battery shutdown bug (32%), I've been struggling to even get an hour SoT, and can go for a short walk with 50% battery and come back with a dead phone.
Huawei refuse to do anything as I do not have original proof-of-purchase for the phone, so my only options are to do things myself or pay someone else.
What are my options here? Will a battery replacement resolve my issues? Replacement genuine batteries seem expensive, are cheap knockoffs to be trusted?
Here is my findings.
I reset my 6P and fully charged. Let it on without using it, it last at least 20 hours and still 59% power left. Then I took 3 photos and it shutdown right away.
I think it is the software issue. Replace battery won't fix it.
Bought my phone used through Swappa and had no proof of purchase, but was still able to convince Google to send me an RMA phone a few weeks ago. Accubattery said the old one had like 70% battery capacity, while the new one is reporting 103% now and my SOT is probably double. So maybe complain away to Google reps until they decide to just RMA it...
Hi, who did you contact for this? I can't find a link on Google's site.
Thanks
Buy a new battery form ebay for 9.99 and it comes with the tools needed to swap with the exception of a x-acto knife or heat gun, but you can use a hair dryer just make sure not to apply heat on the camera or you will have to replace it as well. Buy the one form seller 8-50855 which offers the battery with a temp sensor. The process takes about 20-30 minutes, but it makes a huge difference to have a new battery. Now I get 5-6 hours SoT with heavy usage with pure nexus and custom kernel(Francos) 103% health as well and no more shutting off at 25%.

Unfortunately in the UK they are harder to source.
One thing that worries me is - do you need to glue the phone back together?

they are easy to get in the uk, if you dont trust ebay, i use this company for all my spares for the nexus 6p
https://www.replacebase.co.uk/for-huawei-nexus-6p-replacement-battery-hb416683ecw-3450mah-oem/
also you dont need glue to reassemble the phone, not sure if the battery is held down but if it is, the some double sided m3 tape would do the trick.

Sound, pulled the trigger and ordered off ebay. Now to hope I don't break it taking it apart!
I may end up doing a battery swap also. I;ve had my 6P for 14 months and the battery is only at 65% of it's capacity. This is by far the worst performing battery I have ever had. I'm getting something like 2 hours of SOT. My LG G5, which I've owned longer, has held up MUCH better in the battery department.
I basically move it from charger to charger (car, desk, night stand). I was at an even this weekend and was sure to bring my battery pack to make sure it wouldn't run out of juice during the 8 hours I was there.
I treat my batteries well, and try to never let them discharge below 50% if possible.
I get 2 hours on a VERY good day!
Battery replaced, a little more hassle than it really should be, but let's see how this goes.
As the title says, Phone won't turn on. There are no led lights at all. It does get warm after being plugged in for a little. I had jrkruse's hybrid_bra1 stock safetynet samsungpay...... rom on it. It was rooted. Very minimal processes running. I actually had basically everything stopped and greenify on. Phone was around 40% battery. I plugged it into charger, took my dog outside, showered real fast, washed a few dishes, then came back in to room within 15 minutes to my phone being dead and hot. It's never got this hot before even while rooted and plugged in with this rom on it. I have never had it get that hot. Was just formatted the day before and really bare but, that is what happened.
A couple battery apps I had put the batteries remaining life capacity at around 60%. It held a charge poorly. Even for 60% capacity it felt weak, considering how little I did on it lately. I am thinking the battery may have took a crap but unsure because it warms up when it is plugged in. I plan on getting a battery soon since they are inexpensive and replace it to try it out.
Just wondering if anyone here has any experience with this and can offer any advice.
Thank you in advance.
(I looked for a min or two for similar posts but didn't find much. Will gladly take down if someone can point me the way)
You say your battery was already outworn, It may have died. I think you should try with a new battery, Or take it to a technician who can test the phone's hardware to see if there is anything else broken
i've only had one similar case with an s3, which would turn of at random % of battery. But when plugged turned on. I replaced the battery and it worked fine then

I really do hope that is what's wrong. I just ordered a battery. Thanks for the reply. I also got some little tools and battery door adhesive sticker. Wish me luck!
funny story....
The mic in my Nubia Red Magic broke and I sent that back to hong kong for repairs like 20 days ago. Before the Red Magic, I used this galaxy s7 edge my friend gave me. I gave it back when I got the Red Magic and told him to sell it or something. Not much later, decided to buy it back off of him for $200 to give to my mother. She loved it. I had the gs7 edge with me exploring prepaid provider options for my mom when the Red Magic mic broke. So then I decided to borrow the edge from her till my phone got back and few days later I break this one too..
I feel naked without a phone for so long haha

I have the same rom, with charging issues. I don't think its the rom causing it. The s7e are getting old and the batteries are taking a toll with the age. My phone will charge up to 81 at night and stay there. I get better results with wireless charging so i just top my phone off during the day with my wireless charger. There is a code to reset the battery's internal memory, if i find the link on how to do it I will post here for you.

Thanks for reply and alright let me know if you find out. My phone had no problem charging to 100% Its just the 100% on the status bar wasnt 100% of the 3600 capacity from wear. My friend's also does the same thing as yours except his he cant charge more than like 24% haha. He just uses it as a plugged in music player in car.... I am getting battery in the mail tomorrow and will see what I can do.

A little late, sorry. lol.
Thanks for suggestion, however, I may have worded my statement incorrectly. I meant to say that My phone would charge to 100% and the status bar displayed it as 100% but, the health and total capacity of the battery in mah was not the maximum 3600 or so due to simple wear and tare. It isn't apparent within any stock android feature however, battery monitoring apps like accubattery gather statistics after several charging sessions and estimate the current mah capacity. Mine was much lower than the default oem stated value of 3600. So my battery could be charged 100% but the 100% is really only 2400 mah lol. It was obvious either way by noticing that after my time using it and the previous owner's bad charging over night habits, that the battery was gradually needing charged more often lol..
I did read about the calibration method before when I was first looking into the battery issues. It seems it is more often done after a new battery is installed.
I screwed up a new battery install at the last second. I had to stop due the tiniest little round metal piece coming off from a very light swipe of my plastic spudger.
It was a very small wire connector piece. Unbelievably irritating. I didn't even finish because I doubt it would work properly. I beleive it is for the rf cable or something not sure. The red one on the left bottom side of the logicboard/motherboard whatever. There are three of them.
I took it apart and put it together a couple times prior to this and in a hurry it popped off and I couldnt find it. I couldnt find out the exact part name online so I could buy one and solder it back on. I did find a site/ supplier that has a plethora of them though. They are tiny coaxial connectors/pins. I didn't look through them all but there are 6,000 some listed under coaxial connectors (RF). https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=coaxial pin
I haven't gotten around to asking samsung or the digikeys support if they could help me find out which it is. They have different sizes and frequency ratings or speeds and such. The phone is packed away until I manage to figure out which pin to buy or if I pull 80$ or so out of my behind and buy a whole new motherboard logic board haha.
TL;DR at bottom. For those who like reading, continue..
I recently bought a Nexus 7 for tinkering and nostalgia reasons. I am really impressed that the tablet is STILL supported by custom ROM developers, pretty insane for a 8 year old device. However the battery life was terrible, reporting a capacity of ~56% via Accubattery. That is just poor and almost unusable in my opinion. Off I went on the Google machine searching for a genuine battery, most if not all were fake. I saw mostly photoshopped images of a generic batteries, that don't even look like the original. I did however find one listing of actual "new" genuine Asus/Panasonic batteries but they ship from China, ETA was over a month. Here is that listing for it: eBay link for ~$24. I am very impatient and decided to take a chance on this battery, shipping from California: eBay link The reason I chose this one was because I was about to purchase a battery from iFixit for $30, almost $40 including taxes and shipping. The battery in the second eBay link is the SAME battery shown on the iFixit page for less than half the cost. Insane. One of the reviews reported the battery only had around 83% capacity of 3950mAh with Accubattery, not good.
At ~$16 shipped, 83% capacity is helluva lot better than 56% and decided to go for it. The battery came well packaged along with those super flimsy small screwdriver set, adhesive stips and two plastic prying tools. Don't use the included drivers, they will strip the crap of whatever screw you try to remove. Opening the Nexus is the most tedious part of the battery replacement. I did crack the back casing where the headphone jack port is, it is not that noticable once back together. That area is the thinnest part of the casing and still cracked while being super conservative with prying. Once the back is off the rest of the battery replacement is much easier. Once everything was said and done I powered up the Nexus and the battery was charged to around 80%. And the improvement was already noticeable, the battery did not drain rapidly like the old one did. I drained the battery until it shut off, plugged in the charger and waited. And waited, and waited. It took over three hours for the Nexus to fully charge. And Accubattery reported... 90%! Granted this is just the first battery cycle but for $16 I could not be happier. I do not know if I got lucky with the battery I received but I cannot complain one bit. 90% capacity of 3950mAh! However the battery does suddenly cut off at 3%, something that the original did not do but that doesn't bother me. Draining Li-Ion batteries to 0% degrades them immensely, as well as charging them to 100%. Increase battery life (literally) by keeping the charge from 20-80%. This applies to all devices with Li-Ion batteries.
As for a long term test, we shall see. If the battery does fail prematurely I'll post an update here.
TL;DR: eBay sells the same battery for ~$16 delivered that iFixit sells for over twice the cost. The replacement battery has ~90% capacity of the advertised 3950mAh. Link for battery I bought, same as above: eBay link

Thank you for the link. Another battery power solution for our almost-a-decade-old device is no-battery mod and a cheap 10Ah (or more) power bank glued to the back. In this "configuration" Nexus 7'13 can survive independently of battery supply sources

That area is the thinnest part of the casing and still cracked while being super conservative with prying. Once the back is off the rest of the battery replacement is much easier. Once everything was said and done I powered up the Nexus and the battery was charged to around 80%. And the improvement was already noticeable, the battery did not drain rapidly like the old one did. I drained the battery until it shut off, plugged in the charger and waited. And waited, and waited. It took over three hours for the Nexus to fully charge. And Accubattery reported... 90%! Granted this is just the first battery cycle but for $16 I could not be happier. I do not know if I got lucky with the battery I received but I cannot complain one bit. 90% capacity of 3950mAh! However the battery does suddenly cut off at 3%, something that the original did not do but that doesn't bother me. Draining Li-Ion batteries to 0% degrades them immensely, as well as charging them to 100%. Increase battery life (literally) by keeping the charge from 20-80%. This applies to all devices with Li-Ion batteries.
As for a long term test, we shall see. If the battery does fail prematurely I'll post an update here.
TL;DR: eBay sells the same battery for ~$16 delivered that iFixit sells for over twice the cost. The replacement battery has ~90% capacity of the advertised 3950mAh. Link for battery I bought, same as above: eBay link

Hello
I just got a nexus 7 2012 version from someone for free.
It does not turn on, does not charge. I tried all sorts of things including "jump starting " the battery.
Looks like I fried the battery doing that.
THe battery reads about 3.4 volts but it should be 4.7 volts correct?
Seeing all this, do you think its worth it to purchase another battery to see if this is the problem?
I am thinking its a dead battery with a reading like that, and wont accept charge anymore.
Any idea?
