3pro v4 Battery life and wiring

[Emanuele]

Hi there,
I’ve the same problem. I’ve the 3 pro for a couple of months but yesterday started to shutdown around 30% o random % and say 3% when connected to the charger to start it again (otherwise red empty battery on black screen before boot logo).

Same behavior on windows 10 and linux

Did you find out a way to fix it?

I do have the same problem as you guys. Bought off Geekbuying. Everything worked fine for 3-4 weeks and now my battery will only last about a half hour before it shuts down instantely at about 46%. So basically I can’t use my laptop without having it wired to the AC plug all the time. Not mobile at all like it should be. Geekbuying’s support seems to be terrible; contacted them a lot of times and if by some miracle I got a reply back days later it didn’t help me at all. Already contacted Paypal as well. Hope they’ll help me.

Any advice or help would be appreciated.

Very disappointed. Clearly this seems to be a common error on this laptop.

install batterybar

it´s free

monitor the drain and battery wear

take photos where the date is visible like in my photo.

test this over few days then report back with your findings and photos.

 

my jumper battery runs since 5 months with full day drain and night recharge cycles (so over 100 full cycles)
I get 3-5 hours out of it since I run mostly full brightness and with usb drives and other stuff what discharges often way over 10 Watt.

OK here is some battery usage scenarios.

1. full brightness and full processor usage 16W that would drain our 48w/h Jumper 3s battery in less than  3 hours to shutdown (auto shutdown is between 5% to  10%)
2. full brightness and moderate processor usage 6W that would drain our 48w/h Jumper 3s battery in good 6 hours to shutdown
3. less than 10% brightness and very low processor usage 3W that would drain our 48w/h Jumper 3s battery in 12 hours to shutdown

scenario 2 is for easy work and scenario 1 is for power user, scenario 3 is next to nothing and having all windows services disabled.

the battery is since good 3 months in daily usage and went from 50w/h to 48w/h, now after 5 months it is at 47w/h
