Over a year now with seemingly no one getting what Garmin significantly advertised as key feature & battery life for on this device - and still no significant response or fix from Garmin? Can't trust…
Not so difficult. If you are not a baker (sorry guys), it will go smooth.
Takes max. 20 mins. But it worth.
I am willing to help help if you are keen on it :-)
My 130 died on me this weekend, during a 6 hour ride After about 4 1/2 hour it's screen went blank. There were messages before, at the bottom of my screen, but I could not read them, because I was riding…
The battery life on my Edge 130 is, in a word, dismal. I'm not using the backlight, I have GPS + Glonass set, and a heart meter, and speed/cadence sensors (all Garmin branded). Just 2 weeks ago I did a 90 mile ride and the unit was powered up for 6+ hours with some battery life left at the end. Since then, the unit has twice died after 2.5 - 3 hours of up time. I haven't changed any settings. I did receive a low battery warning for the speed sensor and replaced that battery.
My experience (I’ve got a 130 bought in April 2019, which I acquired second hand in mid-November) is that yes - not even close to 15 hours.
I need to do more detailed experiments but mine ran out of battery today on a ride. I last charged it 5-6 days ago IIRC and during that time about 5 hours in use. Probably 2-3 hours of those paired with a Bluetooth HRM.
I also wonder if it was more than a coincidence that it died when temperatures were down at 2-3C
The gauge is inaccurate ... sometimes it actually goes up in charge!
I reckon the device is not great at holding charge when off and probably needs charging up at least twice a week even if only doing 5-6 hours of use a week ...
Update: I did some careful measurement
Charged during Friday night, used it 3 hours on Saturday, used it an hour today (Monday), and it died. So 50 hours (?) elapsed and only about 4 hours in use, between the need for charging ... hmmm. It was about 0-1C which doesn't help but still ...
I charged mine 2 weeks ago, after my last ride.
Started it up yesterday in diagnostic mode* and it still showed 100%
Took if for a 4 1/2 hr ride and it stil showed 63%. Average temp was 18C.
So Ive got a very good battery, somehow use a lot less energy, or the temperature plays a crucial role.
I use a Ant+ HR sensor, BT phone connection and GPS+Glonass. Backlight is on low setting and minimum time (15s?) FW v3.50.
*In diag mode (startup with the 2 bottom buttons pushed in) you can read battery voltage and charge (for what its worth).
Thanks for the tip on diag mode! Interesting … when I go to that mode it says battery is '4.16' and '92' which I guess means voltage of 4.16v and 92% charged? WHat was interesting is that in non-diag mode that 92 is shown as just 3 bars. The 92 was after a full charge between 10am and 5pm today, and then a 45 min ride home in 3C. Tomorrow morning I will try diag mode again and see how much it loses over 12 hours or so while switched off.
BTW - I turned off phone pairing earlier today too, to see if it makes much difference. If it does - hmmm seems a shame since a slick feature of the 130 is supposed to be the phone notifications ... part of me wonders if ...the 130 is a 'budget' device with most features of the more expensive devices ... but battery life is the key difference (especially given how small the unit is ... I guess the battery is small too).
I use a BT HR sensor, and plain GPS . Backlight is (now) on low setting and minimum time (10s) FW v3.50.
I wonder if BT sensors interfere with BT phone connection.
I also suspect that Garmin Connect needs (4G or wifi) coverage to function. Function between Edge and phone that is, also for simple/basic functions.
Cellphone coverage is fluctuating in the mountains I ride, so I use GC only when I'm at home.
As soon as my 130 dies on me because of low temperature, I'll sell it to someone in the tropics and buy a Bryton 420.
