BlackBerry Bold 9900 Battery JM1

The Blackberry Bold 9900 Battery uses a new li-ion battery. The original battery code is JM1, which is a bit smaller in capacity than the 1550mAh MS1 battery that's been used in the Bold 9000 and 9700/9780. The footprint of the battery is about the same, but the JM1 is definitely thinner as you can see in the comparison shots below. During our press briefing session this week on the device I asked about RIM's expectation of battery life on the 9900 / 9930, seeing as there's a smaller battery but a higher performing processor, and RIM seemed very confident in the battery life. RIM's always put battery life as priority, and they haven't sacrificed the user experience here - so expect the device to power you through a full day of work and play. With the new Bold being the thinnest BlackBerry to date they needed to go with a slightly thinner battery. And for power users who eat through batteries regardless, the good news here of course is that you can always buy a spare battery and swap it out if you need to - I'm glad to see RIM still allowed for a removable battery on the new Bold.
