Yesterday I noticed my battery health was 95%. Today I noticed that it's at 95%. Should I be worried? I've had my MBP for a month and the lowest I've seen it go down was to 98%...
Got a tip for us?

Its very normal. The battery health will change and go up and down during use. Its normal. Now if it dips below 90 and stays, then you have a problem.
Sure you're not talking about the charge? If so, that's normal, as it will fluctuate and the charger will kick in when it gets below 95%.
You might want to calibrate... after a couple calibrations mine stabilized @ 95% after 15 cycles (1st calibration was 5th cycle, 2nd 15th). Now it's at 94% after 102 cycles.
Remember that the health percentage is measured against what the battery is rated for as a spec, but in practice the actual capacity of a fresh battery can deviate from unit to unit. Your MacBook battery is surely down a bit from when new, it's just that you have a battery that started life significantly above spec.
