Err… Why my HTC One X battery life is so poor? Do you always have low battery life issue on your HTC One X? If so, your HTC One X battery might have issue or it is a defect battery. No worry, you can diagnosis HTC One X battery by yourself. HTC has a tool to do so ~ HTC Function Test. Use the Battery Test function in HTC Function Test application to find out your HTC One X battery life performance.

How to test HTC One X battery life?
- Charge battery until 100% fully charged.
- Put HTC One X in Airplane mode (Press and hold power button for 3 seconds and select Airplane mode).
- Bring up HTC Function Test.
- Go to Battery Test.
- Follow onscreen intrusions there.
- That’s all.
My HTC One X battery is perfectly okay because battery level is still above 70% after running battery test. If yours is not, it’s time for you to send your HTC One X back to service.
Sorry Jayce But I Think U Make Mistake By Investing Money In This Handset..You Should Wait For Galaxy S3…
this hand set is nowhere near expectations. i hope the same doesnot happen to s3.
no,no,no,ithink wait for iphone5 cos kill sg3 ha.ha.ha.
people like that, but all smartphone part from Taiwan…youknow…..
In one hour a 12 % decrease is too much and considering it is in air plane mode. How can you say the battery life is ok. I mean i thought my s2 had a poor battery when in one hour with phone and sms sevice on it dropped by 6 – 8%.
4.7″ display with max brightness eats lot of battery.
This is the HTC battery test, not to be confused with actual usage drain.
ooooooooo i was actually considering this. looks like i better wait
This is the HTC battery test, this is what they use if you send it back for repair or a DOA claim, not to be confused with actual usage drain. Everything above 30% is acceptable as stated in the test.

hello jayce,
so, overall, do u recommend htc one x ?
Not a perfect phone. But it does have some advantages that I like. Wait for Samsung Galaxy S III, then decide…
hello jayce,
i tested my htc one x and my battery level reached the limit of 70% after one hour of testing. My battery monitor also indicates overheat after the test. Should i seek manufacturer to replace my device? I only had the htc one x for 1 week.
Yes Jed, do consult HTC Support.
Hi, I’ve done this battery test 2 times, the first time, I was left with 72% and the second time I was left with 75%. I believe it is too low because in your test you have 88% left. I was down to 88% already after 30 mins. Do I have to seek replacement for my device?
Hi Bernard, you can try. 😉
I got 93%
I got 88%
How do I found this HTC Function test?!
Hi Luke, please refer to the guide. HTC Function Test link is there.
