HTC 2600 mAh Rechargeable Battery for One M8

Old battery was dieing at 30/40% or even higher in colder climates, often losing settings on the phone as a result. Was happy with the phone so decided to replace the battery rather than just buying a whole new phone (which sadly seems to be the norm today) It's quite a tricky job to swap these, but there are some good YouTube videos and guides on line showing the process. Just make sure you have the necessary tools before starting otherwise you will likely struggle. Also make sure not to damage to volume button cable which is nestled next to the battery. I initially had an issue where the new battery seemed to be draining very fast, but after calibrating the battery (Basically turning off and then holding Volume up & down + the power button on for several minutes - Google it) I now get loads of life from the battery and it has given my phone a new lease of life.Few weeks down the line and still no issues.

Replacement for my battery in my htc one m8 as when the battery got to 45% it would switch off. Found detailed videos online on how to replace. Would advice buying proper tools if your going to do it yourself, I already have them from fixing a ipod and my parents kindle tablet. Be adviced when doing it that it requires patients as there are lots of parts to remove. I also changed the back case as mine had a cracked camera lens. Should of bought the top and bottom speaker case parts that you have to remove to get to the screws, has I heated it a bit to much on the bottom and it warped it and alot of the glue comes off.New battery makes the phone last like when I got it

Well it's a battery, so I'm not really going to know how good it is for a couple of years, but so far all is good. A little bit fiddly to fit but I bought a tool kit to help the process and it went well. It was for my grandsons phone and he's twenty nine, but if my 70+ year old eyes and fingers can cope it's not brain surgery!Just find a YouTube video and give it a go.

Difficult to install

good price

really improved my battery life, however, you do need to know what you're doing to replace it as it is quite complicated in the htc one m8. it involves taking off the mother board and detaching lots of ribbon wires. but i did it and it works great

As delivered and after installation at cost to me, the battery proved to have an issue of only holding a partial charge. The sellers RTB warranty meant it would cost more to return it than to buy a cheap "knock-off" from the local phone shop, fitted for £25. Poor quality control, and abysmal customer service. Buying original parts isn't always the best solution!

My phone used to die at 30% but now I get to the end of the day sometimes not even getting to 50%.Now my phone should last another 2-3 years:-)
