I’ve had my Fitbit Ultra for quite some time now and have been wondering just how long does the battery last?
Well as the Fitbit website says 5-7 days but a little independent testing never went a miss so lets find out!
Update – If you don’t feel like reading the whole post my Fitbit Ultra lasted a whole 18 days without a recharge!
The testing methodology is that I will fully charge the Fitbit and keep a track on (and publish here) a basic overview of the day, I will record every nights sleep and also point out any gym sessions ect.
So here goes-
Day 1, Monday Evening @ 1806hrs – Now fully charged
Day 2, Tuesday Afternoon @ 1641hrs – Battery showing as high, tracked a full night of sleep and about 5,000 paces during the day
Day 3, Wednesday Evening @ 2348hrs – Battery still at high, another 7,500 paces on top of sleep from last night
Day 4, Thursday Evening @ 2240hrs – Battery now at medium, 8,000 paces today with sleep tracked from last night
Day 5, Friday Afternoon @ 1745hrs – Battery at medium, 6,000 paces today with sleep tracked
Day 6, Saturday – Battery at medium, 14,200 paces today with sleep tracked
Day 7, Sunday Evening @ 1849hrs – Battery at medium, 16,400 paces today with sleep tracked
Day 8, Monday Evening @ 2232hrs – Battery at medium, 8,400 paces today with sleep tracked
Day 9, Tuesday Evening @ 2223hrs – Battery at medium (yes still!), 12,000 paces today with gym session and sleep tracked
Day 10, Wednesday Evening @ 2220hrs – Battery at medium, 5,500 paces today with sleep tracked
Day 11, Thursday Evening @ 2358hrs (up playing Crysis :P) – Battery at medium, 7,300 paces today with sleep tracked
Day 12, Friday Evening @ 2251hrs – Battery at medium, 9,500 paces today with sleep tracked
Day 13, Saturday Evening @ 2352hrs – Battery at medium, 13,300 paces today with sleep tracked
Day 14, Sunday Evening @ 2318hrs – Battery at medium, only 3,500 paces today with sleep tracked
Day 15, Monday Evening @ 2353hrs – Battery at medium (and starting to wonder if its running off of some form of cold fusion), 7,300 paces today with sleep tracked
Day 16, Tuesday Evening @ 2233hrs – Battery at LOW!!!, 5,300 paces today with sleep tracked
Day 17, Wednesday Evening @ 2304hrs – Battery at low, 7,500 paces today with sleep tracked
Day 18, Thursday Evening @ 2238hrs – Battery at low, 8,900 paces today with sleep tracked
I’m afraid that although the battery is not completely drained that here I must end my test…I will be away from my PC for the next 5 days and as such won’t be able to update this post or check the paces/battery status and so its only fair to quit while I’m ahead.
verry useful, any plan to finish your test until the end of the battery life?
The problem with doing that is its very rare that I spend that amount of time near a pc to be able to upload the results every day – either way 18 days is still very impressive.
