    The extra 9 Whr makes a useful difference - potentially 1.5 to 2 hours depending on usage - but still falls short of all-day continuous usage. Also, it's good practice to avoid fully draining a Lithium battery so, for a given usage pattern, the higher capacity battery is going to wear more slowly. Note that you can also stretch the battery time a little by undervolting the CPU using Throttlestop which will also make a small improvement in performance under load by delaying the onset of the thermal trigger to stop the turbo mode.

    Hi I'm considering the latitude 7370 but I'm confused about the weight.
    Dell states 2.48lbs, but some review sites mention 2.6 or 2.7 lbs. I want to get the FHD version with the 43whr battery. Do you know how much above base this is likely to weigh? Is it lighter or heavier than an xps 13?

    That's my current configuration which weighs in at 1.166kg which is 2.57lbs (carbon fibre display back). Dell's weight will be with the smallest battery and possibly lacking some other parts - I can rarely relate the Dell weight to the notebook I receive. Based on the weights at notebookcheck (one of the few review sites which actually weighs notebooks as a matter of course rather than regurgitate the manufacturer's number) the XPS13 is slightly heavier but has a bigger battery.

    Three benefits of the 7370 are (i) zero fan noise; (ii) more key travel; and (iii) lower rated and lighter PSU (it will run on a 3rd party 30W PSU). Features you want / don't want are worth more, in my opinion, than a notebook weight difference of less than 10% while bulky PSUs and their cables can make a big difference in overall portability.

    I bought that external powerbank and it arrived today. The 7370 had this to say about it:
    7370 Power Alert.jpg
    Which means that it will, as I expected, work with the powerbank. The powerbank claims to be 99.16Whr and weighs 0.46kg (1 lb). However, power conversion losses mean that won't all be usable. I tried running the 7370 from the powerbank and my Plugable USB-C power meter showed 19.6V with the current varying between about 0.4 and 0.6 Amps under light usage (ie 8w to 12W power drain) so it should be good for 8 hours running, maybe more. The computer thinks it's on mains power when running from the powerbank so automatic power saving is not enabled. I could customise a power profile to help address this problem. The alternative is to recharge the notebook battery but this increases the power conversion losses.

    I have moved over to this thread now to stop polluting the 7380 thread, my question seems to have been answered about battery capacity - the two m7's on the outlet are both listed as having the palm rest with security features so that explains why they have the lower capacity battery.

    The other question is the screen, I've always opted for 1080p as it can run without scaling and I found the XPS 13 on 8.1 with the QHD+ screen pretty horrible. However I'm tempted by it on the 7370 as I'm liking the 4k screen on the 7275.

    Check which panel is is likely to have. Notebookcheck gives details for anything it has tested. The FHD panel in my 7370 is the Sharp SHP1460 (LQ133M1) which has a display gamut covering 99% of sRGB / 79% of AdobeRGB that puts it in the top league (the FHD panel in the 7380 tested by notebookcheck is the LGD0589 which covers 92% of sRGB / 61% of AdobeRGB).

    Also check the implications of having QHD+ on the battery drain (the GPU has to work harder because of all the extra pixels). My interpretation of the battery run time table in this review is that the higher resolution gives about a 20% hit. That's significant in any situation and made worse if you have the 34Whr battery. If you need a longer time away from the mains then an external battery is an option).

    The GPU doesn't have to work that much harder in 2D mode and I don't think that 20% figure is accurate for normal usage, I have a Latitude 12 with the 4K screen and it doesn't have that much impact on batterylife for the figures I've seen on the 1080p screen.

    John, just wanted to give you a fly-by thank you. Thank you for such informative posts (not just these two, but many others) on information that would be really hard for someone to find otherwise.

    Thanks!

    There's more useful information on the 7370 in the attached review which I prepared but was never published.
